Abstract:
A system includes a pass switch circuit and a first pass switch activation circuit. The pass switch circuit includes an impedance circuit and a pass transistor having a first source/drain connection, a second source/drain connection, and a gate input. The pass switch circuit passes an electronic signal from the first source/drain connection to the second source/drain connection in response to activation of the gate input. An impedance transfer function of the pass switch circuit is determined at least in part by an impedance of the impedance circuit and the impedance is sized to minimize attenuation of the electronic signal due to the impedance transfer function of the pass switch circuit. The first pass switch activation circuit provides a first activation signal to the gate input in response to an enable signal.
