Abstract
A device for testing noise immunity of a circuit includes: an analog circuit, an internal stable reference signal source, an internal power supply module to receive a high level voltage supply, and a signal modulator to provide a noisy signal to the power supply module. The power supply module outputs a noisy power supply to the circuit, in response to the noisy signal, and the device outputs a signal representative of a noise immunity of the circuit. A method includes: providing a high level supply voltage to an internal power supply module, receiving signals representative of the performance of an analog circuit, providing a noisy signal to an input of the power supply module, providing a noisy supply voltage to the circuit, by the power supply module, in response to the noisy signal, and evaluating a noise immunity characteristic of the circuit in response to the received signals.
