New Four-Quadrant CMOS Current-Mode and Voltage-Mode Multipliers

Abstract

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%.

Wide bandwidth CMOS four-quadrant mixed mode analogue multiplier using a second generation current conveyor circuit

“…The multiplier circuits are classified into three groups depending on the operating mode. It can be configured in voltage mode, current mode, or mixed mode and it can be functioned in one-quadrant, two-quadrant [1][2][3], or four-quadrant [4][5][6][7][8][9][10][11].…”

Low-voltage bulk-driven class AB four quadrant CMOS current multiplier

“…Class AB operation of the circuit offers the advantages of high dynamic range and good linearity for low power consumption [2]. Many current multipliers reported in this area are found to be working at C3 V [1][2][3][5][6][7][8][9][10]. In [11] Ravindran et al have proposed a low voltage current multiplier based on class AB operation working at ±1.5 V. The current multiplier developed in this paper operates at ±1 V.…”
