Design and Analysis of Voltage Control Function Generator Using Highly Linear CCII

In this paper, a voltage control function generator using highly linear second generation current conveyor (CCII) is presented. The current architecture of function generator is based on band pass filter (BPF) which simultaneously provides sinusoidal, square and triangular voltage outputs. The proposed circuit implementation utilizes only five CCII and four grounded capacitors. The tunable frequency range of proposed circuit is 25MHz to 47MHz. All circuits have been evaluated using Spectre simulation in UMC 130nm CMOS technology at 1.2V supply voltage.
