High-gain differential CMOS transimpedance amplifier with on-chip buried double junction photodiode

Introduction: The transimpedance amplifier (TIA) is widely used in optical receiver circuits. The majority of CMOS TIA designs reported in the literature are intended for high speed digital signal reception. The TIA reported in this Letter is optimised for low noise analogue optical signal detection, in a situation where a weak modulated optical signal is superimposed on a large DC background. ...

A 2 . 5 V high gain CMOS differential input , differential output single stage amplifier

A high gain, high frequency single stage CMOS op amp is designed and simulated. The authors used gain boosting technique and common mode feedback circuitry on a differential input/ouput 0.5μm CMOS amplifier. Results comprehend a DC gain of 110 dB, a unity-gain frequency superior to 300MHz associated with a phase margin in the range of 60 degrees. Good insensivity to temperature, voltage rail le...

An Enhanced Slew Rate Output Capacitor-free Low Dropout Regulator Based on Differential Transconductance Amplifier

A highly current-efficient and fast transient response capacitor-free low-dropout regulator (LDO) for Systemon-Chip (SoC) applications is presented in this paper. The proposed architecture is implemented using 0.35 μm CMOS technology. The proposed circuit is based on differential transconductance and push-pull amplifier. Common mode feedback (CMFB) resistors and direct voltage spike detection u...
