LATCH COMPARATOR

The invention consists in a single-stage FIA-based comparator with an embedded latch, which is insensitive to input common-mode voltage variations. With respect to the state-of-the-art FIA-based comparator architectures, the invention: a) has a simpler implementation, because of the single-stage topology, eliminating the interface between the pre-amp and the latch; b) does not require the design of additional logic gates to open the reservoir switches since the circuit already incorporates a self-quenching mechanism that automatically stops the reservoir capacitor discharge.
