Claim Text:
1. An apparatus comprising: a first input transistor having a control terminal configured to receive a first input signal; a second input transistor having a control terminal configured to receive a second input signal; a feedback circuit coupled to the first and second input transistors; and first and second cross-coupled transistors configured to provide positive feedback, wherein the first and second cross-coupled transistors are part of the feedback circuit, wherein the feedback circuit is a positive feedback circuit, wherein the first and second input transistors are configured to provide, to first and second nodes, first and second currents according to values of the first and second input signals, respectively, when the feedback circuit is turned on, and wherein the first and second input transistors are configured to produce a reset value on the first and second nodes, respectively, when the feedback circuit is turned off.
