Time-base generator with self-compensating control loop

Abstract From the Canadian patent

A time-base generator with a self-compensating control loop. The time-base generator is suitable for use in level measurement and time-offlight ranging systems. The time-base generator includes a pulse generator stage, a delay stage, a control loop and a references voltage module. The pulse generator generates a transmit pulse train and a receive or sampling pulse train with a delayed timing relationship. The control loop functions with, the delay stage to maintain the desired delay between the first pulse train and the second pulse train. According to another aspect the time-base, generator includes a calibration module. The calibration module generates calibration pulses which are used …
