Title:
PULSE VOLTAGE GENERATION APPARATUS HAVING ADJUSTABLE PULSE WIDTH
Document Type and Number:
WIPO Patent Application WO/2023/221252
Kind Code:
A1
Abstract:
Disclosed in the present invention is a pulse voltage generation apparatus having an adjustable pulse width. The apparatus comprises: a switch control circuit, which is used for generating a control signal; a clock generation circuit, which is used for generating a 50 MHz clock signal; and an adjustable-pulse-width generation integrated circuit, which comprises a phase-locked loop (PLL), a first trigger, a second trigger, a row trigger array, a selector and an XOR gate, wherein the PLL is used for processing the 50 MHz clock signal and then outputting a 400 MHz high-speed clock signal and a 50 MHz clock signal; the first trigger is used for performing rising edge synchronization processing on the control signal to output a synchronization signal; the second trigger is used for performing 20 ns delay processing on the synchronization signal; and each trigger in the row trigger array is used for outputting, under the control of the 400 MHz high-speed clock signal, a plurality of adjustable-pulse-width pulse signals having a stepping precision of 2.5 ns, and then selecting, by means of the selector, a pulse voltage signal of a required pulse width and sending same to a phase change memory. By means of the present invention, a highly precise pulse voltage signal having a rising edge and a falling edge within a range from 20 ns to 100 ns can be generated, the pulse width is adjustable, and the flexibility is high.
