ANALOG-TO-DIGITAL CONVERTER LATCH CIRCUIT

摘要

An analog-to-digital converter latching circuit functions alternatively in a degenerative mode and a regenerative mode. During degeneration, circuit stray capacitances are substantially discharged for resulting in fast operation. When the circuit switches from degeneration to regeneration, a small signal current is able to start the latch in the proper direction without first having to overcome charge stored in the stray capacitances.
