Abstract: A controlled oscillator Analog-to-Digital Converter (ADC) includes an analog interface configured for receiving an analog differential input signal, and configured for providing a differential control signal; first and second controlled oscillators configured for receiving the differential control signal; and a frequency-to-digital converter having a first input coupled to an output of the first controlled oscillator, a second input coupled to an output of the second controlled oscillator, and an output for providing a digital output signal proportional to the analog differential input signal, wherein the analog interface or at least one of the first and second controlled oscillators is configured for receiving at least one disturb signal to prevent locking between the first and second controlled oscillators.

Abstract: Representative implementations of devices and techniques provide analog to digital conversion of an analog input. A multistage modulator using a feed-forward technique can alternately convert integrated samples of the analog input to digital representations. For example, the modulator is arranged to alternately output the digital representations to form a digital representation of the analog input.
