摘要： Circuitry for controlling the oscillation frequency of an oscillator by using a digitally tunable on-chip capacitor bank. The capacitor bank includes a plurality of on-chip capacitors, each of which is independently selectable by a control signal for providing a selectable amount of capacitance to the oscillator to control the oscillator's oscillation frequency.

摘要： A clock oscillator circuit that includes an inverting amplifier and a resonator configured to generate an oscillating signal. The clock oscillator includes a bias circuit having a relatively constant current source configured to create a bias voltage to bias the amplifier in an operating state that can sustain the oscillating signal. The inverting amplifier and the bias circuit are configured to operate in a low power state.

摘要： A circuit for producing a reliable duty cycle for a low power oscillator. The circuit produces a square wave signal based on the differences between the oscillating output signal driven by a piezoelectric crystal and a phase shifted output signal. This circuit provides a quick start for a clock signal, generates a reliable fifty percent duty cycle and is better protected from common mode noise. This circuit can also be configured to be programmable to provide for an adjustable duty cycle.

摘要： Start-up circuit for current mirror circuits to facilitate transition from a zero-current state to an operation state. The start-up circuit includes two sets of current control devices. A set is coupled to each leg of the current mirrored circuit to provide a bias on start-up. The current control devices are coupled together to mirror the current that continues during the operational state such that the start-up circuit in combination with the operating circuit do not draw more current in the operational state than the operating circuit would normally draw in the operational state.
