Abstract
A signal voltage converter converts a 0V to −5V input signal to a +5V to 0V output signal using PMOS transistors for both pull-up and pull-down of the output. Bipolar transistor level shifters and PMOS current mirrors are used to control the pull-up and pull-down transistors in conjunction with a clamp circuit. Output signal transitions are matched for both transition directions to reduce signal timing distortion, and this can be further enhanced by an optional circuit for supplying a controlled current for the clamp circuit.
