位倍乘器(又称权电流发生器)是数字-模拟和模拟-数字转换设备中的一种重要器件,在数字控制、数字通讯、数据处理、遥测遥感、测试测量设备和混合计算系统等许多领域内,有着十分广泛的应用。随着电子计算机技术、特别是微处理机的发展和推广应用,数-模转换器(DAC)和模-数转换器(ADC)已显示出越来越重要的作用。 最初的数-模、模-数转换器是分立元件形式的。现在,计算机已进入集成电路甚至大规模和超大规模集成电路的时代。作为接口电路,分立元件的转换器无论在精度和速度上,都已远远不能满足要求了。集成电路转换器的出现,使转换器的性能指标大大提
Multiplier multiplier (also known as the right current generator) is a digital-analog and analog-digital conversion equipment, an important component in digital control, digital communications, data processing, telemetry and remote sensing, test and measurement equipment and hybrid computing systems In many areas, it has a very wide range of applications. With the development and popularization of computer technology, especially microprocessors, digital-analog converters (DACs) and analog-to-digital converters (ADCs) have become more and more important. The original digital - analog, analog - digital converter is a discrete component. Nowadays, computers have entered the era of integrated circuits and even large-scale and very large-scale integrated circuits. As an interface circuit, the discrete components of the converter, both in accuracy and speed, are far from satisfied with the requirements. The emergence of integrated circuit converters, the performance of the converter greatly improved
