A new solution for a low‐voltage bulk‐driven CMOS operational amplifier is presented in this study. The amplifier is designed using 50 nm process parameters and optimised for 0.5 V supply voltage. The circuit consumes 100 μW, performing 74 dB open‐loop gain, 59 nV/Hz 1/2 input referred noise at 1 MHz and 4.8 MHz gain bandwidth product (GBP) for 20 pF load capacitance.
