Beschreibung
Zusammenfassung:	A device, e.g., a radar transceiver, includes a receiver and a transmitter. One such device includes a phase shifter having a first input to receive an oscillating signal and a second input to receive a control signal. The device also includes a signal generator having a quadrature (Q) channel output to output a quadrature phase version of the oscillating signal; and a Q channel mixer having an input coupled to the Q channel output. A feedback path of the device includes a filter having an output and an input coupled to an output of the Q channel mixer, and an integrator having an input coupled to the output of the filter. The integrator has an output coupled to the second input of the phase shifter, in which the integrator outputs the control signal to the phase shifter.
