Abstract :
This paper proposes the use of the flipped voltage follower as a high speed current sensor for iDD current testing. Simulations in 0.18 μm CMOS technology, as well as experimental results from a breadboard prototype are provided that verify functionality and the potential for high gain-bandwidth of the proposed circuit.
