| 摘 要： | <正> 一、引言 集成模拟乘法器几乎都以Gilbert单元为基础。1986年,Sanchez首先提出用运算跨导放大器(OTA)组成乘法器的新设想,但只用分立元件进行了实验验证,而动态范围等问题均未解决。本文则根据此原理设计并制成一种单片集成模拟乘法器,它具有电路简单、芯片面积小、不需外加放大器等优点。

A New Four-Quadrant Analog Multiplier |
| |
| Abstract: | A new 4-quadrent bipolar analog multiplier was designed and fabricated. This multiplier, differing from traditional one, is composed of two OTAs and characterized by its simple architecture, larger output swing, lower supply voltage, satisfectory frequency response, lower temperature drift and it needs no external amplifier. The operation principle, circuit structure, simulation and experimental results are described in this paper . |
