Patent number: 12270938Abstract: Disclosed active reflector apparatus and methods that inhibit self-induced oscillation. One illustrative apparatus embodiment includes an amplifier and an adjustable phase shifter. The amplifier amplifies a receive signal to generate a transmit signal, the transmit signal causing interference with the receive signal. The adjustable phase shifter modifies the phase of the transmit signal relative to that of the receive signal to inhibit oscillation. A controller may periodically test a range of settings for the adjustable phase shifter to identify undesirable phase shifts prone to self-induced oscillation, and may maintain the phase shift setting at a value that inhibits oscillation.Type: GrantFiled: September 8, 2023Date of Patent: April 8, 2025Assignee: AyDeeKay LLCInventors: Tom Heller, Danny Elad

At a given time, the integrated circuit may be configured to use one or more of the stages in the processing of received signals associated with measurements in an environment. For example, a control circuit or control logic in the integrated circuit may configure the use of one or more of the stages in the integrated circuit.

Publication number: 20250096812Abstract: An integrated circuit includes a set of N unit analog-to-digital converters (ADCs) having a common architecture, and which provide an aggregate data rate. Moreover, the integrated circuit includes control logic that selects subsets of the set of N unit ADCs in order to realize sub-ADCs of different data rates that can each be an arbitrary integer multiple of an inverse of N times the aggregate data rate of the N unit ADCs.
