  • Patent number: 5012205
    Abstract: A balanced oscillator circuit having first and second outputs includes a transistor circuit, having internal parasitic capacitors, for providing first and second output signals at the first and second outputs of the balanced oscillator circuit. An inductor circuit is coupled between the first and second outputs such that the inductor circuit and the internal parasitic capacitors determine the frequency of oscillation of the first and second output signals. The capacitance of the internal parasitic capacitors can be varied by an external voltage applied to the transistor circuit.

  • Patent number: 4937842
    Abstract: A self adjusting data detector receives a modulated carrier waveform and removes the carrier signal, leaving a bandwidth limited waveform. The bandwidth limited waveform represents a digital signal which has lost its squared edges due to the high frequency components which were suppressed during modulation, transmission, and demodulation. The self adjusting data slicer uses a first peak detector to feedback a detector bias voltage to set one peak of the bandwidth limited waveform to a predetermined level. A second peak detector is used to feedback a peak bias voltage to set the opposite peak of the bandwidth limited waveform to a second predetermined level. A data slicer is then able to accurately slice the bandwidth limited waveform at a predetermined magnitude therein recovering the original timing of the digital signal. The data slicer is able to maintain its accuracy over changing modulation levels.

  • Patent number: 4567603
    Abstract: A frequency generator in which the PLL frequency synthesizer and the VCO are directly modulated by an input serial data stream for providing an FSK modulated RF output signal useful in narrowband data communication systems. The serial data stream may alternatively modulate either the PLL frequency synthesizer or the VCO alone.
