Abstract: An apparatus, system, and method for are provided. A device includes a time-to-digital converter (TDC) situated to convert a time-domain signal to a digital value, a delay circuit situated in parallel with the TDC and to delay the time-domain signal by a specified amount of time resulting in a delayed time-domain signal, a time-to-voltage converter (TVC) situated to produce a voltage-domain signal based on the delayed time-domain signal, and a successive approximation (SAR) circuit situated to receive the digital value and the voltage-domain signal and produce a digital-domain version of the input signal.

Abstract: A transceiver may include a transmitter device, a receiver device, a secondary receiver device, and switching elements. The transmitter device may provide a transmit control signal on first and second channels. The receiver device may receive a receive control signal on the first and second channels. The secondary receiver device may monitor occupation of the first and second channels without decoding at least a portion of control signals concurrent with the receiver device receiving the receive control signal. The switching elements may control when the transmitter device provides the transmit control signal to one of and is electrically isolated from first and second antennas, the receiver device receives the receive control signal from one of and is electrically isolated from the first and second antennas, and the secondary receiver device monitors occupation of one of the first and second channels and is electrically isolated from the first and second antennas.

Abstract: A communication device can include a receiver frontend and a wake-up receiver (WUR) frontend. The receiver frontend can have a radio frequency (RF) interface configured to couple to an antenna and a baseband interface configured to couple to a baseband component. The WUR frontend can be selectively coupled to the receiver frontend (e.g. between the RF interface and the baseband interface). The WUR frontend may monitor a communication channel and control the receiver frontend to adjust its operating mode (e.g. waking the receiver frontend from a sleep mode) based on the monitoring. The WUR frontend may have a lower power consumption than the receiver frontend. The WUR frontend and the receiver frontend may share the same impedance matching network and/or the RF interface.
