Differential pair with high output signal crossover |
摘要 |
A buffer circuit includes a differential pair output switch having an additional NPN device and resistor operational to increase the common mode output voltage of the buffer during a switching event, such that the voltage movement at the common emitter node of the differential pair output switch for the buffer circuit is decreased to substantially reduce distortion of an output signal associated with a DAC that employs the buffer circuit.
