A current-mode analog multiplier/divider based on CCCDTA

Low-voltage (LV) low-power (LP) integrated circuit design is becoming a leading trend in VLSI technology, particularly in special portable applications. In this paper, the principle of a bulk-driven MOS transistor is employed in the design of a novel LV LP current differencing transconductance amplifier (CDTA). Designs in the 0.25 µm CMOS technology have been verified via PSpice simulation. The supply voltages are only ±0.6 V.

This study proposes a novel square/triangular wave generator based on a dual outputs differential voltage current conveyor (DO-DVCC). The proposed circuit uses one DO-DVCC combined with three grounded passive components. The presented scheme reveals a compact topology and can produce square/triangular waveform simultaneously. To verify their feasibility, commercially available ICs were used for implementing the prototype circuits. Experimental results revealed consistency with theoretical analyses.

A new multiplier-divider circuit using a single Current Differencing Buffered Amplifier (CDBA) and only six MOSFETs has been presented. The proposed circuit has the advantage of simultaneously realizing a multiplier and divider without changing the circuit topology. The basic functions of the proposed circuit have been verified through PSPICE simulations using a CMOS CDBA and NMOS transistors with process parameters of 0.35 µm CMOS technology and some application results of the proposed cell in various modes of operation have been included.
