The sampling circuit (1001) receives the delay signal (S1000) and performs a sampling operation on the delay signal (S 1000) to generate a sampled signal (S1001). The comparison circuit (1002) receives the sampled signal (S1001) and compares the sampled signal (S1001) with a reference signal (S1004) to generate a comparison result signal (S1002). The power manager (101) receives the comparison result signal (S1002) and adjusts the supply voltage (Vsupply) according to the comparison result signal (S1002).

    Abstract: An ultra-low power clock source includes a compensated oscillator and an uncompensated oscillator coupled by a comparator circuit. In an example, the compensated oscillator is more stable than the uncompensated oscillator with respect to changes in one or more of temperature, voltage, age, or other environmental parameters. The uncompensated oscillator includes a configuration input configured to adjust an operating characteristic of the uncompensated oscillator. In an example, the uncompensated oscillator is adjusted using information from the comparator circuit about a comparison of output signals from the compensated oscillator and the uncompensated oscillator.

    Abstract: During operation of the device, a drive circuit may provide a drive signal having a fundamental frequency to two electrothermal filters ( ETFs ) having different temperature-dependent time constants. In response to the drive signal, the two ETFs may provide signals having the fundamental frequency and phases relative to the drive signal corresponding, respectively, to the time constants of the ETFs. Then, phase-shift values of the phases may be measured using a phase detector, and a signal may be output based on the phase-shift values. Note that the signal may correspond to a value that is a function of a temperature of the device.

    Abstract: An R-C oscillator (200) is configured to vary the two voltage levels that are used to control the oscillation, such that the variation in oscillation frequency with temperature is minimized. A first resistor (R1) is used to control one of the voltage levels, and a second resistor (R2) having a temperature coefficient that differs from the temperature coefficient of the first transistor is used to control the other voltage level. The first resistor (R1) also controls the current used to charge and discharge the capacitor (C) used to effect the oscillation. By the appropriate choice of resistance values, the variations of the control voltages and current are such that the time to charge and discharge the capacitor (C) between the control voltages remains substantially constant with temperature. Preferably the resistance values are selected to also compensate for temperature variations in the delay of the feedback loop.
