摘要： This amplitude control circuit includes a vector composition circuit (18) for generating a cosine wave signal (e3) from a sine wave signal (e1), and a control signal generator circuit (20) for generating, from both sine wave signal (e1) and cosine wave signal (e3), a control signal (e4) which is substantially free from ripple. The direct-current level of the control signal (e4) may vary in proportion to the amplitude of the sine wave signal (e1), but be out of relation to the frequency of the sine wave signal (e1). The amplification of an amplification control circuit (12) is controlled by the control signal (e4) so that the oscillation output signal (e1) form an oscillation circuit (16) is kept constant.

摘要： A crystal oscillator is started in a high power mode for a certain period of time to ensure starting oscillation with average grade crystals, then once the certain time period is over the oscillator switches into a low power mode and sustains oscillation with energy pulses triggered by and synchronized with the oscillator output frequency. These energy pulses may be generated on the positive, negative or both positive and negative edges of the clock output waveform.

摘要： In aspects of a low phase noise technique for use with a crystal oscillator, a bias control circuit sets a bias voltage on the gate of a first transistor needed to sink or source an amount of current corresponding to a sensed common mode signal. The sensed common mode signal is sensed with a common mode sense circuit that is coupled across two ports of the crystal oscillator, and current is provided by a current source. The bias voltage is set by a bias controller that uses a second transistor coupled to the common mode sense circuit and the first transistor.

摘要： An interface to connect sensor equipment and a physiological monitor includes a first connector to receive power from a first channel of the monitor and a second connector to receive power from a second channel of the monitor. The power from each of the first and second channels of the monitor is combined within the interface. The interface further includes a third connector to provide the combined power to the sensor equipment; a voltage converter to rescale the voltage of the combined power that is provided to the sensor equipment; and a scaling circuit to reduce the voltage of a signal representing a measured physiological parameter. The signal representing the measured physiological parameter is sent from the sensor equipment to the monitor. The interface is advantageous to allow sensor equipment to be sufficiently powered by a monitor that would not typically provide enough power.

摘要： A large gain is used to start up the oscillation of the crystal quickly. A control circuit disables a low resistance path based on the measured amplitude to reduce the power dissipation specification of the crystal. Another technique introduces a mixed-signal controlled power supply multi-path resistive array which tailors the maximum current to the crystal. A successive approximation register converts the amplitude into several partitions and enables/disables one of several power routing paths to the inverter of the oscillator. This allows a better match between the crystal selected by the customer and the on-chip drive circuitry to power up the oscillator without stressing the crystal. The "1/f" noise of the oscillator circuit is minimized by operating transistors in the triode region instead of the linear region.

摘要： An oscillator signal stabilization method is provided for a radio transceiver, for example. In the present stabilization method, amplitude variation of a radio frequency oscillator signal generated by a frequency-adjustable oscillator signal generator is stabilized in an adaptive compensation circuit having adjustable compensation parameters. The stabilized oscillator signal is fed from the compensation circuit to one or more frequency dividers for frequency division. The compensation circuit is configured to stabilize signal variations caused by component non-idealities and, thereby, prevent undesired frequency division errors in the frequency dividers.
