| Number | Title | Issue Date |
| 6020790 | Oscillator calibration method and circuit and radio with oscillator In a method of calibration of a voltage controlled oscillator (VCO), the VCO (100) provides an output signal which is used to drive a dividing oscillator (10) such as a relaxation oscillator (RO). The RO has at least two states, one in which the RO provid... | 02/01/2000 |
| 6016081 | Tunable oscillator using a reference input frequency A tunable oscillator includes an input for receiving an input signal from a source of precision frequency such as a CMOS quartz crystal oscillator. The tunable oscillator converts the frequency of the input signal to a first current using a frequency to c... | 01/18/2000 |
| 4642577 | Injection-locked waveguide oscillator An injection-locked waveguide oscillator comprises a first diode (3) having a free-running fundamental frequency above the local cut-off frequency of the waveguide (1) and a second diode (4) having a fundamental frequency below and a higher harmonic above... | 02/10/1987 |
| 4514696 | Numerically controlled oscillator A radio frequency numerically controlled oscillator comprising N one bit adders each providing sum and carry outputs to one of N two bit registers. Sum, carry and frequency selection inputs are combined by each adder to form sum and carry outputs. These r... | 04/30/1985 |
| 4163177 | Oscillation generator providing oscillations of varying amplitude An oscillation generator providing a succession of oscillations repetitively and progressively varying in amplitude includes a feedback oscillator arranged to receive its operating voltage from a capacitor that is progressively charged from a periodically... | 07/31/1979 |
