Abstract

The paper presents a subthreshold four-quadrant multiplier targeted for Teager Energy Operator (TEO) based portable systems. The proposed multiplier functions with balanced input-differential output signals at a 1.2 V supply. The multiplier is simulated using 90nm CMOS process of the BSIM4v4.3 model in LTSpice. The input dynamic range is ±60 mV with maximum non-linear deviation under 4.4% at ±60 mV. Total Harmonic Distortion (THD) is under 0.82% for 20mV amplitudes at 11 Hz, 1 kHz and 10 kHz. The bandwidth of the multiplier is 331.1311 kHz at 5Ω and 10 pF load with a standby power of 4.4361 μW.

基于Teager能量算子的CMOS亚阈值平衡输入-差分输出四象限乘法器

针对基于Teager能量算子(TEO)的便携式系统，提出了一种亚阈值四象限乘法器。所提出的乘法器在1.2 V电源下具有平衡的输入差分输出信号。利用LTSpice中BSIM4v4.3模型的90nm CMOS工艺对该乘法器进行了仿真。输入动态范围为±60mv，±60mv时最大非线性偏差小于4.4%。总谐波失真(THD)低于0.82%的20mV振幅在11hz, 1khz和10khz。该倍增器在5Ω和10pf负载下的带宽为331.1311 kHz，待机功率为4.4361 μW。
