Abstract: In some examples, a circuit includes a phase frequency detector (PFD) having a first input, a second input, and an output. The circuit also includes a control circuit having an input and an output, the control circuit input coupled to the output of the PFD. The circuit also includes a modulation circuit having an input and an output, the modulation circuit input coupled to the output of the control circuit. The circuit also includes an oscillator having an oscillator input and an oscillator output, the oscillator input coupled to the output of the modulation circuit and the output of the oscillator coupled to the second input of the PFD.

Abstract: Examples of circuitry and systems and methods provide a multi-way configurable amplifier to support various applications. The multi-way configurable amplifier may include a reconfigurable filter that comprises first and second inputs adapted to receive an input signal; a fully differential amplifier (FDA); and first and second reconfigurable resistance-capacitance (RC) networks. The FDA has an inverting input, a non-inverting input, an inverting output, and a non-inverting output. The inverting input is coupled to the first input, and the non-inverting input is coupled to the second input. The first reconfigurable RC network is coupled to the non-inverting output, and the second reconfigurable RC network is selectively couplable to the inverting output. The reconfigurable filter is configurable to enable operation in any of multiple modes including a single-ended mode of operation and a differential mode of operation.

Abstract: A device includes a voltage converter and an analog to digital converter (ADC). The voltage converter includes an input to receive a first voltage and an output to output a second voltage based on a switching signal having a first discrete converter frequency and a second discrete converter frequency. The ADC is coupled to and proximate to the voltage converter. The ADC includes a digital filter configured to substantially attenuate a first filter frequency and a second filter frequency. The voltage converter further includes a frequency control device configured to set the first discrete converter frequency and the second discrete converter frequency so that the first discrete converter frequency is approximately equal to the first filter frequency and the second discrete converter frequency is approximately equal to the second filter frequency.
