基于0.18μm CMOS工艺的电流型模拟运算电路
Current mode analog operational circuit based on 0.18 μm CMOS process
摘要
Abstract
A new CMOS current mode multifunction analog operational circuit with low voltage and low power consumption is proposed,which can run multiplier,squarer,divider and different types of controllable gain amplifiers. The design is based on translinear principle,in which MOSFET is adopted and runs in the subthreshold region. The proposed circuit is composed of six inter⁃matching transistors to form two overlapping tranlinear loops. The circuit is based on 0.18 μm CMOS process,and sup⁃plied with ± 0.6 V low voltage DC source. The circuit was verified by simulation of Tanner TSpice software. The simulation re⁃sults show that when the circuit is configured as an amplifier,its frequency is about 1.5 MHz at -3 dB,linear error is 0.63%, total harmonic distortion is 0.08%,and maximum power consumption is 1.16 μW.关键词
