This paper demonstrates the design of low voltage, low power CMOS op-amp using DTMOS technique for low-power applications. The design goal is to achieve high gain, phase margin and minimum power dissipation at lower supply voltage. DTMOS transistor is proposed in this paper for the design of op-amp which replaces the normal CMOS transistors for designing a low power, low voltage two stage op-amp. A dc gain of 96. 38 dB, a phase margin of 71. 46º by achieving a unity gain bandwidth of 4. 077 MHz while operating at 1V supply voltage. The performed simulation results show a power dissipation of 12. 19 µW is achieved under 5 pF load in this design. The design and analysis is performed using 180 nm CMOS technology in Cadence Virtuoso ADE.
