Abstract :
The design for high speed ΣΔ modulator is discussed, Comparison between current-mode and switched-capacitor ΣΔ modulator performance is given. Fast-speed CMOS amplifier and comparator are designed to implement the circuit. In 1.08 μm CMOS process current-mode ΣΔ modulator achieves 100 MHz sampling rate
