此种乘法器也可作除法器。电路利用双极模拟开关,特点是精度高,成本低,尺寸小。 用少量标准部件,能制作一个比大多数目前流行的部件更精确的乘法器/除法器。 虽然它的频宽是低的(小于100HZ),定做组件的精确度比单片跨导乘法器高二个数量级。仅仅另偏差需要调整。在25℃能获得±0.01％的直流精确度,而-55℃到125℃是±0.1％。 如果利用混合微电子包装技术,能获得不大于单片组件的电路。
This type of multiplier can also be used as a divider. Circuit using bipolar analog switch, characterized by high precision, low cost, small size. With a small number of standard components, it is possible to create a more accurate multiplier / divider than most currently popular components. Although its bandwidth is low (less than 100Hz), the precision of custom components is two orders of magnitude higher than monolithic transconductance multipliers. Only the other deviations need to be adjusted. DC accuracy of ± 0.01% at 25 ° C and ± 0.1% at -55 ° C to 125 ° C. If the use of hybrid micro-packaging technology, can not be greater than the single-chip components of the circuit.
