Abstract:
A receiver for receiving a digitally coded radio-frequency signal from a transmitter, comprising:an RF detector for detecting the digitally coded radio-frequency signal and for generating a digital signal responsive to the digitally coded radio-frequency signal, the RF detector comprising an analog amplifier coupled to an analog oscillator for generating an analog oscillator signal and a digital signal generator responsive to the analog oscillator signal for producing the digital signal;a clock signal generator for producing a clock signal;a delayed clock signal generator for generating a first offset clock signal and a second offset clock signal in response to the clock signal; anda first comparator for comparing the second offset clock signal with the digital signal and producing a combination clocked and analog bias signal and supplying the combination clocked and analog bias signal to the oscillator to stabilize the oscillator timing;a second comparator for comparing the first offset signal with the digital signal and generating a detected code signal in response thereto.
