A novel four quadrant analog multiplier (FQAM) is presented using the recently proposed active building block (ABB), namely the dual-current-controlled current di®erencing bu®ered ampli¯er (DCC-CDBA). The inputs to the circuit are two bipolar current signals and current and voltage outputs are available as multiplication of the input signals. The use of DCC-CDBA in four quadrant multiplier design is attractive, since the circuit structure is very simple and uses reduced number of components, viz. only one DCC-CDBA, which is constructed using two second-generation current controlled conveyors (CCCIIs). The circuit operation is currenttunable and ideally temperature insensitive. The workability of the circuit is veri¯ed using PSPICE simulations.

In this paper, a four-quadrant current-mode multiplier based on a new squarer cell is proposed. The multiplier has a simple core, wide input current range with low power consumption, and it can easily be converted to a voltage-mode by using a balanced output transconductor (BOTA) [1]. The proposed four-quadrant current-mode and voltage-mode multipliers were confirmed by using PSPICE simulation and found to have good linearity with wide input dynamic range. For the proposed current-mode multiplier, the static power consumption is 0.671 mW, the maximum power consumption is 0.72 mW, the input current range is ±60 µA, the bandwidth is 31 MHz, the input referred noise current is 46 pA/ √ Hz, and the maximum linearity error is 3.9%. For the proposed voltage-mode multiplier, the static power consumption is 1.6 mW, the maximum power consumption is 1.85 mW, the input voltage range is ±1V from ±1.5V supply, the bandwidth is 25.34 MHz, the input referred noise voltage is 0.85 µV/ √ Hz, and the maximum linearity error is 4.1%.
