This paper gives a comparative analysis of an inductorless Complementary Metal Oxide Semiconductor (CMOS) Single-ended current-mode Transimpedance Amplifier (TIA) intended for use in front-end Optical communication for wideband operation. This technique uses N similar TIAs in parallel configuration to boost the overall bandwidth as well as the transimpedance gain which is not possible with volt...

In this paper design for 1 volt rail to rail supply voltage output of operational amplifier with common mode feedback amplifier has been presented. The circuit has been simulated using BSIM4 model with 50nm CMOS process. The simulation results show that output voltages for the modified operational amplifier are swinging from 10mV to 990mV i.e. between the rail to rail supply voltages (0 to 1V)....

An active RC filters with a 880 / 1760 MHz dual bandwidth tuning ability is present for 60 GHz unlicensed band applications. A third order Butterworth low-pass filter utilizes two Cherry-Hooper amplifiers to satisfy the very high bandwidth requirements of an amplifier. The low-pass filter is fabricated in 90nm standard CMOS process. Drawing 6.7 mW from 1.2 V power supply, the low frequency gain...
