Abstract

A simple, stable frequency and temperature-insensitive circuit is disclosed for correcting distortion in cathode ray tube (CRT) display systems. More specifically, the circuit comprises a ramp generator 10, a differential transistor pair 50, a current generator 40 and an output stage 50. Ramp generator 10 comprises transistor 14, resistors 16 and 18, capacitor 15, together with amplifier 12 to generate a linear ramp. The differential transistor pair 50
