Abstract
A system and method have been provided for passively isolating a latch circuit. The method provides a latch having a first input, an output, and a reset port. The latch first input is selectively connected to a first reference voltage. While the latch first input is connected to the first reference voltage, the latch is reset. Subsequent to disconnecting the latch first input from the first reference voltage, a first node is selectively connecting to the latch first input. In response to selectively connecting the first node, a first analog signal is supplied to the latch first input. Subsequent to resetting the latch, the first analog signal is captured and the latch output supplies a digital signal responsive to the captured first analog signal.
