新型高频高线性CMOS跨导线性电流模乘/除法器设计
Novel High-frequency High-linear CMOS Translinear Current-mode Multiplier/Divider
摘要
Abstract
In view of the shortcoming of conventional CMOS current multiplier/divider in low linearity and low frequency,a novel CMOS current mode multiplier/divider based on MOS Translinear rule,with square-root and squarer/divider circuit for core circuit, is proposed. HSPICE simulation test using TSMC's 0. 35 μn CMOS process model show a -3 dB bandwidth of 35.1 MHz for the circuit,working at a supply voltage of 3 V,and its static power consumption is 202. 68 μW,output current range 0~25.1 μA, nonlinear error 0. 85% and total harmonic distortion 0.14%. Compared with the multipliers/dividers designed by Tanno,Lopez,et al. ,the proposed multiplier/divider circuit has many advantages,using -3 dB band width, reduced power consumption, reduced power supply voltage, improved linearity, raised accuracy,and a relatively more advanced 0. 35 μm CMOS technology,and saving chip area.关键词
