A low power consumption RF receiver system that is adapted for receiving and
shaping
transmitted digital data signals into a digital data stream for processing by a
microprocessor is provided. The receiver system comprises an integrated circuit,
which includes a data slicer adapted to accept the received digital data signals,
shape the signals into a digital data stream, and pass the digital data stream
to the microprocessor. The integrated circuit further includes a peak detector
adapted to sense ambient circuit noise when digital data signals are not present,
develop a voltage reference signal representative of the peak value of the ambient
circuit noise, and pass the voltage reference signal to the data slicer. The receiver
system further includes a support circuit between the peak detector and the data
slicer that has a voltage divider and a charge capacitor that is adapted to accept
the voltage reference signal and produce a clamping reference for the data slicer
thereby preventing the data slicer from responding to ambient circuit noise and
passing false digital data streams to the microprocessor.
