Abstract

Electrical buffer output circuitry includes a first high branch having a high signal input terminal, a low input branch having a low input signal input terminal, and a signal output for the buffer circuitry. Either the high branch or the low branch is turned on in response to a signal at one of the input terminals, and the resistance of the turned on branch is varied as a function of time to improve the speed and noise characteristics of the buffer until the output voltage stabilizes.
