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.

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.
