Abstract: A system and method for detection of an event and recording data associated with the event. An application-specific integrated circuit (ASIC) for event-driven data acquisition from detector is disclosed. The event-driven circuitry stays silent when there is no event detected on the detector. The event-driven data acquisition system consumes small power and may consume no memory during waiting for an event. Once the event arrives (e.g. photons, particle or ion hits the detector panel), the event is detected and recorded. The ASIC includes multi-channel ADCs (or ADC arrays) with flexible resolution which enables an option to operate at a lower resolution during the silent period to save power.

Abstract: Systems and methods are provided in which a voltage-controlled oscillator for a radio transmitter includes a LC tank circuit, and a muting circuit. The LC tank circuit includes an inductive element and a capacitive element; wherein the inductive element of the LC tank circuit includes the antenna of the transmitter. The muting circuit can include a variable resistor connected in parallel with the LC tank circuit.
