Abstract

An improved differential integrator and related circuitry is disclosed. In one exemplary embodiment, the improved differential integrator comprises an integrating gain boosted cascode circuit for receiving an input signal having a first locking time and for generating an output signal having a second locking time, wherein the second locking time being delayed by a predetermined amount from the first locking time. The improved differential integrator may also comprise a multi-node common-mode feedback circuit, and a dynamic cascode common-mode feedback circuit. The integrating gain boosted cascode circuit may include a gain boosted cascode structure and a capacitor compensation structure. The multi-node common-mode feedback circuit may include a folded cascode circuit. The dynamic cascode common-mode feedback circuit may include a cascode circuit that uses common-mode feedback.
