ABSTRACT:
An active termination resistor is provided within a feedback loop circuit thus advantageously increasing the stability of the feedback loop circuit. In particular, the active termination resistor traces the impedance of the feedback loop such that R(f).congruent.1/GM3(f). The active resistor may also be configured to track the value of the resistor to set the feedback transconductance over process and temperature variations to ensure stability of the feedback loop over these variations.
