摘要： Over-voltage indicator and related circuit and method. The over-voltage indicator can work with an I/O circuit of a chip for detecting over-voltage in an I/O pad and providing an indication signal accordingly. When over-voltage does not happen, the over-voltage indicator continues to detect a signal level of the I/O pad and keeps the indication signal low. Once over-voltage is detected, the over-voltage indicator pauses detecting, asserts a high level in the indication signal, and periodically resumes detecting until end of over-voltage is detected. With informing provided by the indication signal, a core cell of the chip can perform proper operation to reduce potential damage caused by over-voltage.

摘要： A signal comparison circuit is provided. The signal comparison circuit includes a first amplifier, a second amplifier, a peak detector, and a comparator. The first amplifier is a zero-peaking amplifier. The first amplifier receives and amplifies a data signal. The second amplifier receives and amplifies a reference voltage. The peak detector is coupled to the first and the second amplifiers for detecting and maintaining maximum values of the amplified data signal and the amplified reference voltage, and then outputting the maintained data signal and the maintained reference voltage. The comparator is coupled to the peak detector for comparing the maintained data signal with the maintained reference voltage and outputting a result of the comparison.

摘要： A signal detection circuit is used for detecting signal squelch of a differential input signal to generate a corresponding digital output signal. The signal detection circuit includes: a reference voltage generator for generating a reference voltage of which the common mode voltage tracks the common mode voltage of the input signal; a real-time signal judgment circuit, real-time rectifying and amplifying a difference between the input signal and the reference voltage; and a deglitch circuit, sampling and/or amplifying an output signal of the real-time signal judgment circuit, and transforming sampling results into the digital output signal to reflect signal squelch of the differential input signal.
