A Wide-Range Voltage-to-Time Converter

The principle of operation of a novel linear time-delay circuit is described. The circuit is based on the Miller integrator principle and incorporates the ramp-generating function, the amplitude comparison, and the resetting action into a gate-generating circuit. The linearity of the sweep voltage is the highest possible that can be obtained with one transistor ramp generator. Wide delay range with a single timing capacitor and high duty cycle is obtained.
