摘要： 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.

摘要： A voltage domain crossing circuit and method are disclosed. In one embodiment, the voltage domain crossing circuit comprises an AC coupling component, a DC biasing component and a high voltage output amplifier. The AC coupling component receives an input low voltage signal and AC couples and splits the signal into two voltages. The two voltages are then DC biased to a predetermined bias voltage using the DC biasing component. The high voltage output amplifier then amplifies the biased voltages in the high voltage domain yielding a signal in the high voltage domain. Other embodiments of the voltage domain crossing circuit and method are also disclosed.
