چکیده :
This paper introduces the design of an innovative ultra-low-voltage bulk-driven CMOS operational amplifier. A significant feature of this design is the implementation of a cross-connected differential pair that utilizes the bulk-driven technique to effectively reduce the supply voltage. Furthermore, the addition of auxiliary transistor pairs greatly enhances the transconductance voltage gain of the circuit, enabling the differential amplifier to achieve a high voltage gain even at lower supply voltages. The intermediate stage of the proposed amplifier consists of a common-source amplifier with an active current mirror load, improving voltage gain while ensuring that the input and output signals are in-phase. Additionally, the output stage is designed for high current output and low output resistance, addressing the difficulties posed by high output capacitive loads. Simulations conducted using 50nm BSIM4 CMOS technology at a supply voltage of 0.5V revealed an open-loop gain of 82.6dB and a power consumption of 125μW. The input-referred noise was recorded at a competitive level of 34nV/√Hz at 1 MHz, and the resulting unity-gain bandwidth was measured at 5.2MHz with a 10-pF load capacitor.
