Abstract: An apparatus and method for processing signals in the analog domain. A signal is derived from analog circuit properties that is shift and scale invariant. Although the circuit properties are not quantized as in traditional digital signal processing, the signal is immune from effects of the properties, such as common mode noise, absolute voltage or current level, finite settling time, etc., as a digital signal would be. The shift and scale invariance allows for mathematical operations of addition, subtraction, multiplication and division of signals. By combining these operations, various circuits may be constructed, including a voltage controlled amplifier, a time gain amplifier, and an analog-to-digital converter. The circuits are constructed using almost no non-linear, active devices, and will thus use less power for a given speed than comparable digital devices, and will often be faster as there are no delay elements and no need to wait for the circuit properties to settle.

Abstract: An analog element for use as a neuron in a recurrent neural network is described, the analog element having memory of a prior layer state and being a continuous time circuit rather than having a discrete clocking interval. The element is characterized and described by the Laplace s-domain operator, as distinct from a digital solution that uses the z-domain operator appropriate for quantized time descriptions. Rather than using an all-pass filter, the analog equivalent of a unit delay in the z-domain, a finite gain integrator, which is a simpler circuit, may be used to provide the delay in the analog s-domain. The resulting circuit may be easily implemented at the transistor level.

Abstract: A method for performing a fast Fourier transform. The bin spreading effect of conventional FFT methodology may be removed by a mathematical technique that relies on an incomplete replacement of the input data sequence. In the present approach this replacement is accomplished by a “round robin” method. In this approach no window function is required and the FFT calculation proceeds after each new sample is added round robin fashion to the input sequence. The resulting output bins from the FFT show the signal evolution with time, overlapping as in the known art but by a single sample. The output of a FFT so constructed is not time invariant, but rather there is a rotation present in each output bin when viewed as an analytical signal. This rotation is predictable and hence removeable, but is also exploitable as a means to remove the bin spill over.

Abstract: A programmable impedance element consists of a plurality of nominally identical two-port elements, each two-port element having an impedance element and two switches, the two-port elements arranged in a chain fashion with a structured set of switches such that a range of impedances can be obtained from each cell by dynamically changing the connections between the impedance elements in the cell. The common cell is constructed by connecting the nominally identical two-port impedance elements in a way that the number of possible combinations of the impedance elements is reduced to the subset of all possible combinations that uses the minimum possible number of connections. This structure allows the creation of matched impedances using industry standard devices. The connections between impedance elements are switches that may be “field-programmable,” i.e., that may be set on the chip after manufacture and configured during operation of the circuit, or alternatively may be mask programmable.

Abstract: Described herein is a system and method for controlling a computing system by an AI network based upon an electroencephalograph (EEG) signal from a user. The user's EEG signals are first detected as the user operates an existing controller, during which time the associated artificial intelligence (AI) system learns by correlating the EEG signals with the commands received from the controller. Once the AI system determines that there is sufficient correlation to predict the user's actions, it can take control of the computing system and initiate commands based upon the user's EEG signal in place of the user's actions with the controller. At this point, weights in the AI network may be locked so that further commands from the controller, or the lack thereof, do not reduce correlation with the EEG signals. In some embodiments, the AI network may initiate commands faster than the user would be able to do.

Abstract: An apparatus and method for using the known phenomena of quantum gate tunneling in semiconductor transistors to define the DC state of a charge-coupled amplifier is described. A first stage in which the tunneling current is bipolar (by pairing PMOS and NMOS transistors) in combination with a second stage with a controlled common mode voltage that can be used to control the first stage tunneling current, and thus the common mode voltage at the input. This can be done without the use of additional elements that may degrade performance or power consumption, since the input devices both process the input signal and maintain the DC operating point of the circuit. The approach may be advantageously used not only in charge-coupled amplifiers as described herein, but also in other capacitively coupled circuits such as charge balancing analog to digital converters (ADCs) and digital to analog converters (DACs).

Abstract: An apparatus and method for determining signals representative of events in the environment of a reactive transducer while being driven by a switching amplifier is disclosed. While the switching amplifier is in a zero voltage state, a signal capture circuit that is also in a zero voltage state is connected to the transducer for a relatively brief period of time during which a measurement is made of the residual current flow due to the inductance of the transducer. A prediction of the output signal is then subtracted from the signal measured across the transducer, reducing the overall range of the signal and increasing the relative size of the back-EMF signal compared to any remaining output signal. If desired, conventional echo cancellation can then be performed. The back-EMF signal can then be subjected to further processing by an analog-to-digital converter as known in the art.

Abstract: A signal processing circuit that achieves functionality similar to that of a switched capacitor circuit without the necessity a clock. The circuit compensates for finite open loop gain and for offset voltages in the components, allowing the circuit to “calculate” the result of a problem represented by the circuit essentially immediately upon the presentation of a new input or set of inputs. After the circuit is initialized to remove gain, an input is applied to the circuit, and propagates through the network and affects the state of amplifier outputs; the propagation from the input through capacitors to the ultimate output(s) of the circuit is the analog calculation taking place. The calculation is not mediated by a clock, but rather the calculation corresponds to the circuit's one-time response to the application of the inputs. Using these techniques complex signal processing circuits and even analog neural networks may be constructed.
