摘要：

This paper proposes an on-chip 96.5% current efficiency CMOS linear regulator using a Flexible Control technique of Output Current (FCOC), By the use of the FCOC technique, the proposed circuit realizes to drive a flexible output current according to the load current variation. Therefore, the proposed linear regulator can supply stable output voltage using the FCOC technique, The linear regulator is fabricated by double-metal 1.2-mum CMOS technology. The number of transistors is 16 and the die size is 0.423 mm(2), The fabricated linear regulator achieves a fluctuation of output voltage less than 6.81 mV(p-p) at a frequency of output current f(I-out) ranging from 1.8 Hz to 100 MHz, Moreover, the fabricated on-chip CMOS linear regulator can achieve 96.5% current efficiency.
