Abstract
A circuit for converting received input signals to highly symmetrical CMOS level outputs having fast slew rates. The circuit can accept a differential input signal with a wide range of common mode voltages. A first stage level shifts the input signals to provide a ground-based common mode output to a second stage level shifter which centers the input signals around the midpoint between V.sub.cc and ground and which increases their voltage swing. The final stage provides a full, highly symmetric, rail-to-rail output capable of driving highly capacitive loads at high rates and which is immune to temperature, V.sub.cc, and process variations.
