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.

Systems and methods for testing electrical connections between a chip and external circuitry

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.

Deriving a capacitance-ratio information, device and method

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.
