摘要： Apparatus and methods for compensating supply sensitive circuits for supply voltage variation are provided. An electronic system includes a power supply that outputs a supply voltage having a nominal voltage level, a supply conductor for routing the supply voltage, and a group of integrated circuits (ICs) that each receive the supply voltage from the supply conductor. Each IC includes a supply sensing circuit that generates a sense signal based on a local voltage level of the supply voltage at the IC, a bias control circuit that adjusts a bias signal based on the sense signal to account for a difference between the nominal voltage level and the local voltage level of the supply voltage, and a signal processing circuit biased by the bias signal.

摘要： Scalable 2D joint phase-time arrays (JPTA) support multiple simultaneous RF beams without sacrificing array gain. A 2D JPTA comprises M antenna groups that each comprise N antennas, each coupled to one of N phase shifters. The array comprises M delay elements configured to: apply a time delay to a first signal to be transmitted by one of the antenna groups while each phase shifter in the group phase shifts the time-delayed first signal and feeds the phase-shifted-and-time-delayed first signal to the corresponding antenna, or apply the time delay to a second signal received from the group while each phase shifter phase shifts a third signal received from the antenna, the second signal being a combination of the phase-shifted third signals. The time delays produce a beam spread in a first dimension of the array such that multiple beams are formed in different directions.
