Patent GB-2089601-A (GB)
Title: Phase Sensitive Detector
IPC: H03D13/00
Filed: 1980-12-12
Abstract: A phase sensitive detector comprises four D-type flip-flops 701 to 704 which are so interconnected that in response to data pulses DP and clock pulses CK they produce respective pulse sequences D1 to D4. An exclusive OR-gate 705 receives the pulse sequences D2 and D3, and an exclusive OR-gate 706 receives the pulse sequences D1 and D4. Depending on the occurrence of the data pulses DP relative to the clock pulses CK, the pulse sequences D3 and D4 will occur early or late relative to the pulse sequences D1 and D2. As a result, the logic outputs from the gates 705 and 706 will proportionately control two current sources 708 and 709 of a current source circuit 707 to drive current into and extract current from a capacitor 203. The voltage across the capacitor 203 serves as a control voltage for synchronising the clock pulses CK, with the data pulses DP. <IMAGE>
