本文提出的是一个输入矩形波,以周期—电压转换为基础的同步脉冲倍频器。其电路的一个特征是输出和输入波形有相同的占空比。倍频因数可用一个数控电位差计来达一、引言在文献中,提出许多用不同硬件合成的方法倍频,但最常用的倍频方法是用锁相技术(Bilgic1982,)。其它倍频方法是用一个几个频率倍加器的级联,结果得到一个倍增系数2~n。这些频率倍增电路常使用频 This article presents a synchronous square wave multiplier based on a cycle-to-voltage conversion of an input rectangular wave. A feature of the circuit is that the output and input waveforms have the same duty cycle. Frequency multiplication factor can be reached by a digital potentiometer. Introduction In the literature, many methods of multiplication by different hardware are proposed. However, the most common frequency doubling method is the phase-locked technique (Bilgic 1982). Other frequency doubling method is to use a cascade of several frequency doublers, resulting in a multiplication factor of 2 ~ n. These frequency doubling circuits often use frequency
