A 93.36 dB, 161 MHz CMOS operational transconductance amplifier (OTA) for a 16 bit pipeline analog-to-digital converter (ADC) / Nordiana Mukahar and Siti Hawa Ruslan

A 93.36 dB, 161 MHz CMOS operational transconductance amplifier (OTA) for a 16 bit pipeline analog-to-digital converter (ADC) / Nordiana Mukahar and Siti Hawa Ruslan

A gain modified CMOS Operational Transconductance Amplifier (OTA) for a 16 bit pipeline Analog-to-Digital Converter (ADC) is presented. The circuit is designed to be used for a high resolution and low sampling rate ADC. Gain boosting technique is implemented in the design to achieve high DC gain...
