Abstract
This paper presents a new four-quadrant analog multiplier based on a dynamic threshold MOS (DTMOS). The attractive features of this DTMOS transistor-based multiplier are its supply voltages and total power consumption, which were determined as ± 0.2 V and 18.4 nW, respectively. In addition, the study found no influences of the bulk effect of the transistors used in the proposed multiplier circuit. The layout of the four-quadrant analog multiplier occupied an active area of 44.6 µm × 21.93 µm and was drawn using Cadence Environment software, while the post-layout simulation results were performed using Cadence Environment with 0.18 µm TSMC CMOS technology parameters. All theoretical results and post-layout simulations confirmed the performance of the proposed circuit.
