Abstract

A specific application CMOS voltage follower is presented, which is well suited to be used as a component of VLSI analog electronics such as hardware implemented artificial neural networks (ANN's) or switched-capacitor filters (SC-filters). The main advantages of the follower are: a very high precision of operation and low power consumption. Another advantage is a low input capacitance (about 2fF) and extremely high input resistance. Compared with general purpose followers, its disadvantage is a restricted range of input voltage variations. This is the price we pay for the achieved positive features. Apart from the general idea and some previous versions of the follower, a new circuit realization is presented. SPICE simulation results concerning layouts made for a 0.35mum CMOS process are shown. These results are in good agreement with theoretical predictions as well as experimental results achieved for a 0.8mum prototype. Prototypes designed for the 0.18mum technology are currently being fabricated (in cooperation with University of Alberta in Canada) and no measurements have been performed yet

用于硬件信号处理的高精度低功率电压从动器

介绍了一种特殊应用的CMOS电压跟随器，它非常适合用于VLSI模拟电子元件，如硬件实现的人工神经网络(ANN)或开关电容滤波器(sc -滤波器)。从动件的主要优点是:操作精度非常高，功耗低。另一个优点是低输入电容(约2fF)和极高的输入电阻。与通用从动器相比，其缺点是输入电压变化范围有限。这是我们为实现积极特性所付出的代价。除了一般的思想和以前的一些版本的从动器，提出了一个新的电路实现。给出了0.35 μ m CMOS工艺版图的SPICE仿真结果。这些结果与理论预测以及0.8 mm原型机的实验结果很好地吻合。为0.18 μ m技术设计的原型目前正在制造中(与加拿大阿尔伯塔大学合作)，尚未进行任何测量
