We propose a novel class-AB second-generation Current Conveyor (CCII) based on the class-AB Flipped Voltage Follower (FVF) topology, and compare it with a class-A CCII based on the conventional FVF. The AB-FVF is capable of driving larger capacitive loads, showing faster settling. Furthermore, it can drive the Z output with currents larger than the biasing ones, improving power efficiency. A modification of a previously published FVF is also introduced to improve the compensation of the frequency response.

Abstract
We propose a novel class-AB second-generation Current Conveyor (CCII) based on the class-AB Flipped Voltage Follower (FVF) topology, and compare it with a class-A CCII based on the conventional FVF. The AB-FVF is capable of driving larger capacitive loads, showing faster settling. Furthermore, it can drive the Z output with currents larger than the biasing ones, improving power efficiency. A modification of a previously published FVF is also introduced to improve the compensation of the frequency response.| File | Dimensione | Formato | |
