Abstract: The present invention relates to a system and a method for pulse width modulation and demodulation of a continuous input signal, which system is configured to receive a continuous input to an analog modulator, which system comprises a demodulator generating a continuous output signal. It is the object of the pending patent application to use an analog modulator for transmitting the signal from the input stage over to an output stage. A further object of the pending patent application is to preserve the signal integrity in regard to precision and to minimize both non-linearities and distortion side effects. The object can be fulfilled by the analog modulator being formed as a composite phase modulator which composite phase modulator comprises at least one feedback loop which feedback loop determines the width of a low-level discrete signal, which composite phase modulator comprises at least one feed-forward loop, which feed-forward loop determines the width of a high-level discrete signal as a function of the continuous input. Hereby it can be achieved that timing between discrete low-level and high-level forms a discontinuous output signal representing the continuous input.

Abstract: A low-power power supply for an electronic circuit uses an existing current input and converts the current to a higher voltage sufficient for supplying an electronic circuit. The input current generates a defined input voltage, which input voltage is initially generated by voltage drop by the input current passing at least one diode in the open direction of the diode. The input voltage, through a transistor, charges a plurality of switched capacitor networks in a first mode of operation, and in a second mode of operation, the switched capacitor networks are coupled in series for multiplying the input voltage to second higher voltage that is supplied to a oscillating circuit. The oscillating circuit drives the input current via a transformer and half bridge driver to convert a low voltage current supply from a low voltage current into a low current and higher voltage useable for supplying a small electronic circuit.
