A leakage compensation circuit includes a compensation digital to analog converter (DAC) and an adjustment circuit. The compensation DAC is configured to: receive a first digital signal associated with a transmitter of a transceiver; generate a compensation analog signal using the first digital signal; and provide the compensation analog signal to a receiver of the transceiver. The adjustment circuit is configured to generate the first digital signal by adjusting a second digital signal from the transmitter based on one or more adjustment parameters.

Method and apparatus for a transceiver system

Methods and apparatus are described for detecting both single event latch-up (SEL) and electrical overvoltage stress (EOS) using a single, reconfigurable detection circuit. One example circuit capable of detecting a latch-up state and an overvoltage condition generally includes an impedance element coupled to a power supply node; a voltage divider coupled to the power supply node; a multiplexer having a first input coupled to a tap of the voltage divider, a second input coupled to a first portion of the impedance element, and a third input coupled to a second portion of the impedance element; a reference generator; and an analog-to-digital converter (ADC) having a first input coupled to an output of the multiplexer and a second input coupled to an output of the reference generator.

Configurable single event latch-up (SEL) and electrical overvoltage stress (EOS) detection circuit

A circuit for implementing a multifunction output generator is described. The circuit comprises an amplifier circuit having a first input and a second input; a voltage generator coupled at a first node to a first input of the amplifier circuit; a controllable current source configured to provide a variable current to the first node; and a switching circuit enabling the operation of the amplifier circuit in a first mode for sensing a temperature and a second mode for providing a reference voltage. A method of implementing a multifunction output generator is described.
