Abstract

In this paper, a method to reduce the second order effects on the circuit performances caused by the small sized MOS transistors is proposed. A current mode square-root circuit, a squarer/divider circuit and a multiplier/divider circuit are designed using this method. Proposed circuits have been simulated with SPICE simulator using 0.35 μm CMOS technology parameters. The main advantages of the proposed circuit are reduced errors of the output current function, a smaller area on the chip, possibility of controlling the output current with the control voltage, operation at higher frequencies and more efficient power consumption. As a result, it can be considered as a useful building block for IC designer.
