A Design of Analog Multiplier and Divider Using Current Controlled Current Differencing Buffered Amplifiers

A novel current-mode analog multiplier/divider, based on current controlled current differencing buffered amplifiers (CCCDBAs), is presented in this paper. The proposed circuit employs only two CCCDBAs without any external passive element requirements. It can work as either a multiplier or a divider, without changing its topology. In addition, the proposed circuit can work as a gain-controllable current amplifier. The circuit performances are depicted through PSPICE simulations. The simulated results show that, for plusmn1.5 V power supply, the total harmonic distortion is about 0.317% at 1 MHz, the -3 dB bandwidth is approximately 26.42 MHz, the maximum input range is about plusmn100 muA and the output current is minimally sensitive to temperature variations.
