Abstract :
In this paper a new 0.35 μm CMOS technology second generation current conveyor (CCII) is presented. It is a low power (60 μA @ ± 1.5 V power supply) circuit, featuring 88 × 100 μm2 area, 100 MHz bandwidth and 10 GHz equivalent gain bandwidth (GBW) product. Its static and dynamic characteristics when used both as a voltage and current buffer are described. The chip has been fabricated and tested, and experimental results are discussed. Its use in an application as an instrumentation amplifier (IA) is also presented. The CCII based IA has weaker offset and better CMRR than its voltage mode equivalent. In order to cancel output offset voltage and reduce noise, the IA´s input and output signals are chopped at high frequency.
