Continuous-Time ΣΔ ADC with Implicit Variable Gain Amplifier for CMOS Image Sensor

Continuous-Time ΣΔ ADC with Implicit Variable Gain Amplifier for CMOS Image Sensor

This paper presents a column-parallel continuous-time sigma delta (CTSD) ADC for mega-pixel resolution CMOS image sensor (CIS). The sigma delta modulator is implemented with a 2nd order resistor/capacitor-based loop filter. The first integrator uses a conventional operational transconductance amplif...
