Abstract: In a latch circuit having a bistable pair of cross connected transistors of a first polarity and a third transistor of a second polarity, a current signal greater than a bias current is received at a latch circuit port, amplified with the third transistor, and applied to the latch circuit port. This decreases the time in which the latch circuit port receiving the current signal greater than the bias current reaches a steady state voltage.

Abstract: A differential comparator with improved bit-error rate performance operating with a low supply voltage. The differential comparator includes a first pair of transistors receiving a differential input. A second pair of transistors is coupled to the first pair of transistors. A pair of resistive elements is connected between the first pair and second pair of transistors so as to increase bias currents shared by the first and second pairs of transistors. The increased bias currents reduce a time required by the differential comparator to transition from a meta-stable state to a stable state, thereby improving a bit-error rate of the differential comparator. The resistive elements can use linear resistors or transmission gates. Gates of either the first or second pair of transistors can provide an output.

Abstract: A method for reducing bit errors in an analog to digital converter having an array of comparators. The outputs of first and second comparators are received as in inputs to an Exclusive OR gate. The first and second comparators are separated in the array by a third comparator. The output of the Exclusive OR gate is used to determine if the third comparator is in a metastable condition. If the third comparator is in a metastable condition, the bias current of the latch circuit of the third comparator is increased to increase the rate at which the third comparator transitions to a steady state.
