Abstract
A signal translator for converting an input voltage (V.sub.I) into an output voltage (V.sub.O) at a different level contains a primary element stack (10) and a similarly-configured image element stack (12), both coupled between the sources of a potentially first variable supply voltage (V.sub.CC) and a normally constant second supply voltage (V.sub.EE). A reference voltage (V.sub.R) is supplied to both a primary-stack transistor (Q2) which provides the output voltage and an image-stack transistor (Q4) which provides a feedback signal (V.sub.F). A feedback circuit (14) formed with an amplifier (16) and a shifting circuit (18) response to the feedback signal to supply the reference voltage at such a value as to compensate the output voltage for changes in the first supply relative to the second supply voltage is particularly useful for CTL-to-TTL logic.
