摘要： An oscillation device includes an oscillator, an oscillation detector that detects an oscillation of the oscillator and outputs an oscillation detection signal, a phase shift controller that generates a phase shift signal to provide the drive signal as positive feedback to the oscillator, and an amplitude detector that detects an amplitude of the oscillation detection signal and outputs an oscillation amplitude signal. The oscillator is controlled based on the oscillation amplitude signal and the phase shift signal.

摘要： A Geiger-Mueller charge particle rate measurement system includes a clock management unit in combination with multiple oscillators and rate feedback controller to allow for reactive switching between the different oscillator frequencies to optimize system use. Controlling the clock management unit to send the appropriate frequency (clock signal) to the timers in response to measured rate date from the rate feedback controller facilitates operation at different clock speeds, which helps reduce power consumption when operated at lower speeds.

摘要： A first capacitor has a capacitance adjustable to a set point value by application of a bias voltage. A second capacitor also has a capacitance adjustable to a set point value by application of a bias voltage. The first and second capacitors are arranged to receive the same bias voltage generated by a control circuit. The control circuit receiving the set point value as an input and generates that bias voltage in response to a quantity representative of a capacitance of the second capacitor.

摘要： An oscillation device includes an oscillator, an oscillation detection unit that detects oscillation of the oscillator and outputs an oscillation detection signal, and a drive unit that generates a drive signal in keeping with the oscillation detection signal and outputs the drive signal to the oscillator. The drive unit includes a phase shift unit that shifts the phase to provide the drive signal as positive feedback to the oscillator. The phase shift unit includes a disturbance generating unit that outputs the periodic signal, a fluctuation unit that causes the amount of phase shift to fluctuate based on the periodic signal, a drive amplitude detection unit that detects the amplitude of the drive signal and outputs a drive amplitude signal, a product detection unit that outputs a detection signal after performing product detection on the drive amplitude signal based on the periodic signal, and an adjustment unit that adjusts the phase-shift amount based on the detection signal.

摘要： Techniques are generally described herein related to filters including first operational transconductance amplifier (first OTA) and a second operational transconductance amplifier (second OTA). In some examples described herein, the first OTA and second OTA have substantially the same transconductance. The first and second OTAs can be configured to realize filters such as first-order all-pass filters, second-order all-pass filters, higher-order all-pass filters, and quadrature oscillators.
