Abstract: An electro-static discharge (ESD) protection system for a wireless transceiver comprises a switch circuit at a first terminal and a second terminal of a low noise amplifier; a primary ESD protection circuit between an input terminal and a low voltage supply terminal of the wireless transceiver for shunting a first source of current of an ESD event; a clamp element between a high voltage supply terminal and the low voltage supply terminal having a clamping voltage that is less than a breakdown voltage of the LNA for preventing a second source of current of the ESD event from receipt by the LNA; and a power supply ESD clamp element between the high voltage supply terminal and the low voltage supply terminal for shunting a third source of current of the ESD event at the high voltage supply terminal.

Abstract: Systems and methods for testing electrical connections between a chip and external circuitry are discussed. In some embodiments, a chip may include an Input/Output (I/O) terminal and a test circuit coupled to the I/O terminal, wherein an oscillating frequency of the test circuit changes in response to an impedance change at the I/O terminal due to a connection failure or degradation.

Abstract: Aspects of the present disclosure are directed to injection locking and related apparatuses. As may be implemented in accordance with one or more embodiments, an apparatus includes a plurality of injection-locking circuits configured to receive an injection signal, each injection-locking circuit including a mixer and a lock-detection circuit. In each of the injection-locking circuits, the lock-detection circuit detects a lock-status relationship between the injection signal and a signal output from the injection-locking circuit. In response to the lock-status relationship indicating an unlocked condition, a phase/magnitude of the injection signal is adjusted. In response to the lock-status relationship indicating a locked condition, transmission of an FM continuous wave (FMCW) chirp signal is facilitated.
