Abstract
The present invention relates to a circuit and method for generation of trigger signals for a radar level gauging systems. A pulse-width modulator, has an input connected to a pulse-repetition-frequency generating oscillator. A monostable multivibrator, has an input connected to an output of the pulse-width modulator. First and second integrators are connected to an output of the pulse-width modulator and the monostable multivibrator respectively. A voltage summation element, is connected to an output of the first and second integrators respectively and at least one control signal input. A servo regulator provides a control loop between an output of the voltage summation element and a control port of the pulse-width modulator. A reference clock output is provided at the output of the monostable multivibrator and a second clock output is provided at the output of the pulse-width modulator.
