An emitter-coupled differential comparator compares a horizontal rate ramp signal with a vertical-frequency parabola in a television context for producing horizontal rate pulses duration-modulated at the vertical rate. The comparator is arranged to compensate for a temperature-dependent differential-mode component of the signal sources. The compensation is provided by a temperature-responsive element coupled in the emitter circuit of one of the emitter coupled transistors. |
