Patent ID: 8258819

Claim:
An apparatus comprising: a voltage rail; a series-shunt amplifier having: a pre-amplifier having a first input terminal, a second input terminal, a first output terminal, and a second output terminal, wherein the first and second input terminals of the pre-amplifier receives a differential input signal; a first inductor that is coupled between the voltage rail and the first output terminal; a second inductor that is coupled to between the voltage rail and the second output terminal; a third inductor that is coupled to the first output terminal; and a fourth inductor that is coupled to the second output terminal; and a latch that is coupled to the third and fourth inductors, wherein the latch is activated during a hold phase and deactivated during a track phase, wherein the latch includes: a first grounding transistor that is coupled between third inductor and ground so as to provide a first path to ground for the third inductor in the tracking phase; and a second grounding transistor that is coupled to fourth inductor and ground so as to provide a second path to ground for the fourth inductor in the tracking phase.
