Abstract:

 

In this paper, a new CMOS four-quadrant analog multiplier   circuit is proposed, based on a pair of dual-translinear loops. The   significant features of the circuit are its high accuracy and high linearity   as well as its body effect-free operation, owing to the fact that the   circuit relies on a new dual-translinear topology. In addition, harmonic   distortions are precisely discussed due to their conceivable mismatches,   including transconductance and threshold voltage of the transistors. HSPICE   postlayout simulation results are presented to verify the validity of the   theoretical analysis, where under a supply voltage of 2.8 V, the bandwidth   of the proposed multiplier is 137 MHz, and the corresponding maximum   linearity error remains as low as 1.12%. Moreover, the power dissipation   of the proposed circuit is found to be 521 μμ\mu W. The presented multiplier   is expected to be useful in the design of various analog signal processing   applications such as modulators and frequency doublers, as illustrated in   this paper.
