摘要： An on-chip true noise generator including an embedded noise source with a low-voltage, high-noise zener diode(s), and an in-situ close-loop zener diode power control circuit. The present invention proposes the use of heavily doped polysilicon and silicon p-n diode(s) structures to minimize the breakdown voltage, increasing noise level and improving reliability. The present invention also proposes an in-situ close-loop zener diode control circuit to safe-guard the zener diode from catastrophic burn-out.

摘要： Methods and apparatus for detecting ultra wide-band signals using circuitry having nonlinear dynamics characteristics are disclosed. The receiver circuit can be implemented using a simple tunnel diode or using an op-amp to provide dynamic characteristics. The detector can be used in a variety of modulation schemes, including but not limited to an ON-OFF keying scheme, an M-ary pulse position modulation scheme, and a pulse width modulation scheme. The approach requires only a single frame to detect the signal.

摘要： A method and apparatus are provided for generating output pulses or oscillations in response to input analog waveforms which involves exciting, with a known but arbitrary analog waveform, a circuit with a variable operating point and having a transfer function characterized by an unstable operating region bounded by a first stable operating region and a second stable operating region. The analog waveform is characterized by having a first information region and a second information region. In response to sensing the first and second information regions, the operating point of the circuit is forced into its unstable and stable regions. This produces a sequence of oscillatory and non-oscillatory behavior at the circuit's output.

摘要： A loadline bias circuit for biasing solid state devices operable at high frequencies is disclosed. The source impedance of the dc bias circuit is adjusted to influence the RF device characteristic, thereby creating a way to optimize the device performance. The bias circuit comprises a resistive element coupled in series connection with a constant voltage source or in parallel connection with a constant current source. The bias circuit may be adapted to set an optimum relationship between the bias current and bias voltage so that when one bias parameter changes, the other will automatically compensate with an appropriate change as well. The resistive element provides a device operating range throughout which the bias power supplied to the device is substantially constant. The value of the loadline, that is, the resistive element, can be selected to optimize particular performance parameters.
