Abstract
A state of one or more fuses can be determined using a common-gate FET device to read reference information and test information from a fuse bank. In an example, the FET device can be selectively diode-connected using a first switch that responds to a control signal, and a signal-storing capacitor can be connected to the gate terminal of the FET device. The capacitor can store information about a reference signal when the first switch is closed and a first input signal is applied at a source node of the FET device. When the first switch is open, a second input signal can be applied at the source node of the FET device, and an output signal at the drain node of the FET device can indicate a magnitude relationship between the first input signal and the reference signal. In an example, the second input signal can indicate a state of a fuse.
