    Abstract: A comparator circuit's signal range can be enhanced using an input signal attenuation circuit. In an example, a comparator circuit receives an input signal and a reference signal. The input signal can be conditioned by one or both of the attenuation circuit and a conditioning circuit, and a resulting conditioned signal can be presented to a compare element. Under first operating conditions where the input signal is approximately equal to the reference signal, the attenuation circuit can be substantially bypassed and a first resulting conditioned signal can be presented to the compare element. Under second operating conditions where the input signal is substantially greater than the reference signal, the attenuation circuit receives a portion of the input signal and a different second resulting conditioned signal can be presented to the compare element.

    Abstract: A signal amplitude detection circuit includes a detector and a trimming algorithm module, and the detector having a preset baseline threshold reference value and an output terminal connected with the trimming algorithm module which is arranged for recording and decoding an output result of the detector to output an amplitude code value, and generating a control signal for controlling the baseline threshold reference value rise to a power supply level from a ground level or drop to the ground level from the power supply level, and the output result of the detector being “1” if a crossover occurs between the baseline threshold reference value and the detected signal; otherwise being “0”. The signal amplitude detection circuit detects the signal amplitude in a digital way, which has simpler structure, lower power consumption, reduced size of chips, and stable and accurate detection result without PVT drift.

    Abstract: A Folding Comparator circuit which receives an analog input current and both compares it to a DC reference current while at the same time folding the input current around the reference current to be passed on as an output current which can then be passed on to another folding comparator stage. A series of such stages connected together with some XOR logic gates can perform an analog to digital conversion process as a pipeline of auto-folding stages which will instantly convert analog signal to digital signal.
