The AB-CCII, a novel adaptive biasing LV-LP current conveyor architecture

We present a low voltage low power architecture for an integrated current conveyor (CCII) topology, designed to decrease the stand-by power dissipation without affecting the CCII transient performance. In the proposed circuit, implemented in a standard AMS 0.35 um CMOS technology, an extra current flows into the circuit only when an input voltage variation occurs (through the adaptive biasing technique), so improving the transient response speed without a substantial increase of the average power consumption. Simulation results confirm the expected theoretical considerations
