Abstract

The invention provides a signal waveform converting circuit. The signal waveform converting circuit comprises an electronic switch unit and a differential motion output unit, wherein the electronic switch unit converts an input signal into two in-phase output signals, and the signal waveform converting circuit outputs a difference value between two in-phase output signals and converts the input signal into a direct current signal; as the input signal is not required to be converted into a steamed bread wave and then converted into the direct current signal, the problem of precision decrease caused by introducing of a diode when the input signal is converted into the steamed bread wave is solved, and the problem of long delay caused by introducing of a capacitor when the steamed bread wave is converted into a direct wave signal is solved.

Description

technical field [0001] The invention relates to the technical field of signal waveform conversion, in particular to a signal waveform conversion circuit. Background technique [0002] The signal waveform conversion circuit is a circuit used to convert the input signal of sine wave, triangle wave, square wave, etc. (or other waveforms, such as white noise signal, sawtooth wave, etc.) into another signal form. The existing waveform conversion circuit Such as figure 1 shown. [0003] Assuming that the input signal VIN is a sine wave, when the input signal VIN is greater than the reference voltage VREF, the diode D1 is cut off, and the diode D2 is turned on. At this time, the output signal Vout is figure 2 The graph of middle region I; when the input signal VIN is less than the reference voltage VREF, the diode D1 is turned on, and the diode D2 is cut off, the input signal VIN passes through the resistor R14 and the operational amplifier A2, and the output signal Vout is fi...
