RECTANGULAR VOLTAGE GENERATOR Russian patent published in 2000 - IPC

FIELD: converters, in particular, master oscillators for automatic control and regulation equipment. SUBSTANCE: device has N channels, each of which has phase frequency tuning oscillator, which includes phase comparator, which output is connected through low-pass filter to voltage- controlled oscillator, which output is connected to second input of phase comparator and serves as device channel output. In addition each channel is equipped with comparator with N resistors and phase shifting unit. Inverting input of comparator is connected through N-1 resistors to outputs of rest N-1 channels, and through Nth resistor to output of voltage-controlled oscillator. Output of said comparator is connected through phase shifting unit to first input of phase comparator. EFFECT: increased reliability and precision. 1 dwg
