ABSTRACT:
A circuit for providing an improved “feed forward” zero in a feedback loop such that the zero has a frequency dependent on the transconductance (gm) of a common gate transistor, and pole and zero separation that is dependent on a multiple of the gm. The circuit includes an error amplifier and a compensation circuit. The compensation circuit provides a first feedback current and a second feedback current. The error amplifier receives a reference signal and a feedback signal. The feedback signal is provided by summing the first feedback current and the second feedback current.
