摘要
This paper presents a novel ring amplifier for continuous-time (CT) circuits. The proposed amplifier enables the usage of ring amplifier in continuous-time applications. The design parameters of the proposed architecture are discussed and analyzed. A CT second order Sigma-Delta (Sigma Delta) modulator is designed using the proposed architecture achieving SNDR of 61.7 dB at signal BW of 1 MHz and sampling frequency of 104 MHz. The modulator is implemented in a 65 nm CMOS process and consumes 490 mu W from a single 0.9 V power supply.
