Abstract: A device including at least one processor, and an analog-to-digital (ADC) circuit, wherein the at least one processor is configured to generate an excitation signal and provide the excitation signal to a crystal in a pierce oscillation configuration, wherein after providing the excitation signal, the ADC circuit is configured to obtain as input a signal output from the crystal and convert the signal to a digital output; the at least one processor is configured to compare the digital output of the ADC circuit to a plurality of thresholds and based on the comparisons is further configured to drive the crystal to cause the crystal to operate as a pierce oscillator and to generate a clock signal from at least of one of the comparisons.

Abstract: According to an example, an electronic device includes a component, a supply line providing a supply voltage, a transistor with a control input, a linear first control loop, and a non-linear second control loop. The transistor outputs an output voltage to the component depending on a signal applied to the control input. The linear first control loop includes an ADC to convert an analog output voltage level into a digital measurement signal, a controller to generate a digital control signal for the transistor depending on the digital measurement signal, and a DAC to convert the digital control signal into a first analog control signal. The non-linear second control loop is configured to generate a second analog control signal depending on the analog output voltage level. The second analog control signal is superimposed with the first analog control signal and the combined control signals are fed to the control input of the transistor.
