A NOVEL DESIGN OF CURRENT MODE MULTIPLIER/DIVIDER CIRCUITS FOR ANALOG SIGNAL PROCESSING?

In analog signal processing, current is used as input variables. In this design current mode multiplier /divider circuits is implemented in two modes. Thus implementing the circuit with proposed concept has very small linearity errors. In addition, high linearity is achieved because high accuracy current mirrors are adopted and the output current is insensitive to the temperature. The proposed computational structures are designed for implementing in 0.18-μm CMOS technology, with a lowvoltage operation (a supply voltage of 1.2 V) excepting with the power consumptions are 55 and 70 μW, respectively, while their frequency bandwidths are 79.6 and 59.7 MHz, respectively.
