title = "A Low Noise Operational Amplifier with Cascode Frequency Compensation Technique for Voice Detection and Recognition",
abstract = "This paper proposes a low noise operational amplifier for voice detection and recognition. The transistor level low noise technologies and the cascode frequency compensation are presented in this design. This work has been implemented in a 180 nm CMOS process and simulated with a 2 V power supply, a 200 kOmega resistive load and a 220 pGamma capacitive load. The proposed amplifier consumes an area of 282 mum times 332mum and a total quiescent current of 109.258 muA. And it achieves a closed loop gain of 2.96205 dB, a unity gain frequency of 3.18 MHz with 40.2 phase margin and an input integrated noise of-109.5S5 dBV within 20 Hz-20 kHz (an input referred noise at 1 kHz of 2S.61nV/Hz).",
