Claim of US Patent No. 9,049,080

1. An injection-locked RF receiver having trifilar transformer splitter, comprising:
a trifilar transformer splitter, having a primary winding, a secondary winding and a tertiary winding, the trifilar transformer
splitter receiving an RF input signal inputted to the primary winding, the secondary winding outputting a first differential
signal and the tertiary winding outputting a second differential signal;

an injection-locked oscillator, connected to the secondary winding and generating a differential oscillation current signal
according to the first differential signal; and

a phase detector, connected to the tertiary winding and the injection-locked oscillator and generating an amplitude signal
according to the second differential signal and the differential oscillation current signal.
