摘要： A circuit for generating differential reference voltages, a circuit for detecting a signal peak, and an electronic device. In the circuit for generating reference voltages, a common-mode extraction circuit receives a first differential signal and a second differential signal, extracts a common-mode level from the first differential signal and the second differential signal, and applies the common-mode level to a non-inverting input terminal of a first operational amplifier. The first operational amplifier, a main control switch, a first voltage dividing resistor, a second voltage dividing resistor, and a first direct current power source constitute a feedback loop, to generate differential reference voltages matching with the common-mode level. Adjusting a current provided by the first direct current power source can change the differential reference voltages, obtaining a reference for to-be-detected amplitude of the signals. Signal amplitude is detected with high precision, and detection reliability of a peak detecting circuit is improved.

摘要： A peak detector circuit includes a first capacitor coupled to an inverter and a first switch in parallel with the inverter. An input of the inverter couples to second and third switches. The second switch couples to an input voltage node. The third switch couples to an output voltage node of the peak detector circuit. The peak detector circuit includes a second capacitor coupled to the third switch and a third capacitor coupled to the second capacitor by way of a fourth switch. The third capacitor couples via a fifth switch to a power supply voltage node or a ground. A periodic control signal causes the first, second, and third switches to repeatedly open and close and a second control signal causes the fourth and fifth switches to open and close to adjust an output voltage on the output voltage node towards an input voltage on the input voltage node.
