New second-generation current conveyor negative (CCII—) realization suitable for very large scale implementation is described. The proposed architecture provides a very low impedance level at the X terminal and a wide dynamic voltage range, aswell as a high current tracking accuracy. Simulations show that the CCII— current follower bandwidth extends beyond 100 MHz. Two compensation methods are discussed: the first results in voltage-offset cancellation, while the second results involtage-offset compensation as well as Rx reduction.
