Abstract: A circuit with a sampling network may include a pair of capacitors, where each of the capacitors has a first node and a second node; a first pair of switches communicatively coupling corresponding differential input voltage signals to the first node of each of the capacitors; and a second pair of switches communicatively coupling the second node of each of the capacitors to a common mode voltage source. Corresponding differential output voltage signals at the second node of each of the capacitors may be communicatively coupled using a differential switch. The second pair of switches may be coupled in parallel with the differential switch. A clock signal of the differential switch may be de-asserted prior to de-asserting corresponding clock signals for each of the second pair of switches.

Abstract: A modulated signal based on a low-precision, fast startup oscillator is provided to a circuit with a high-precision, slow startup oscillator. The frequency of the modulated signal ranges around the characteristic or resonant frequency of the high precision oscillator without using feedback from the high precision oscillator circuit. An implementation can include one or more variable gain circuits that can be adjusted based on an amplitude threshold in relation to the output signal of the high precision oscillator circuit.

Abstract: A method and device for testing a digital-to-analog converter is provided. The method may include configuring a decoder to address an individual unit cell of a plurality of unit cells of a digital-to-analog converter. The configured decoder may select a particular unit cell of the plurality of unit cells for testing. The selected unit cell may have digital and analog circuitry. A bias current of the selected unit cell may be increased. The increased bias current of the selected unit cell may be greater during the testing than during normal operation. A test logic signal may be applied to the selected unit cell. In response to the test logic signal, an output signal may be output from the selected unit cell logic circuitry of the digital-to-analog converter. A device may include logic circuitry configured to select an individual unit cell for testing and a current generating circuitry.
