Abstract :
A new current sensing circuit with bulk control (CCB) technique is presented in this paper. Compared to several current sensing techniques, there is a trade-off between the sensing accuracy and speed. Thus, the proposed CCB technique can achieve high-speed current sensing without sacrificing much sensing accuracy owing to the improved large loop gain of bulk control and current mirror based technique. Simulation results demonstrate the verification of the design methodology in the current sensing designs.
