Abstract
A circuit and method configured to generate a variable impedance. The circuit may comprise a voltage controlled resistor configured to generate the variable impedance in response to (i) a first transistor configured to receive a first control signal and (ii) a bias transistor configured to receive a bias signal. In one example, the variable impedance may be generated in further response to a clamp transistor.
