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.
