Abstract

The invention discloses a sine wave pulse signal generation circuit and a related electronic device. The sine wave pulse signal generation circuit comprises: an inductor, a first end of which is coupled to a first reference voltage; a capacitor, wherein the first end of the capacitor is coupled to the second end of the inductor, the second end of the capacitor is coupled to a second reference voltage, and the first reference voltage is higher than the second reference voltage; a first diode, wherein the anode of the first diode is coupled with the first end of the capacitor; a first switch which is coupled between the cathode of the first diode and the second reference voltage, wherein the sine wave pulse signal generating circuit generates a sine wave pulse signal at the second end of the inductor, the sine wave pulse signal has a pulse period, the pulse period comprises a first time period and a second time period, in the first time period, the voltage of the sine wave pulse signal is fixed, and in the second time period, the voltage of the sine wave pulse signal is not fixed and is a sine wave.

Description

technical field [0001] The present application relates to a circuit, in particular to a sine wave pulse signal generating circuit and related electronic devices. Background technique [0002] In modern electronic sensing technology, sinusoidal pulse signals, such as sine wave pulse signals, are often required. In some applications, it is necessary to generate sine waves with high frequency and peak-to-peak voltage, such as frequencies in tens of megahertz and peak-to-peak voltages in excess of hundreds of volts. Existing circuits for generating the above sinusoidal pulse signals often have the disadvantages of excessive circuit power consumption and / or excessive circuit size. Therefore, how to solve the above problems has become one of the urgent problems in this field. Contents of the invention [0003] One of the objectives of the present application is to disclose a sinusoidal pulse signal generating circuit and related electronic devices to solve the above problems. ...
