摘要： A differential multiplexer includes a plurality of multiplexing circuits. Each multiplexing circuit inputs a corresponding differential input signal including a positive input signal and a negative input signal, and outputs positive and negative output signals. Each multiplexing circuit includes first, second, third and fourth transistors. The first and second transistors input the positive input signal. The third and fourth transistors input the negative input signal. Outputs of the first and third transistors are connected to the positive output signal. Outputs of the second and fourth transistors are connected to the negative output signal. The positive and negative output signals are controlled using gate voltages on the first and fourth transistors. The second and third transistors are turned off when the differential multiplexer is in use. The transistors are cross-coupled to make leakage between the positive and negative input signals common mode in the positive and negative output signals.

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.

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.
