Improved SNR Integrator Design with Feedback Compensation for ∑∆ Modulator
Varun Mishra,  Abhishek Bora,  Vishal Ramola
This paper represents a method to improve the SNR and linearity of an integrator by feedback compensation technique. The discussed design reduces signal swing while keeping advantages of both feed-forward as well as feedback topology without changing the signal transfer function. SNR and linearity are related to the output of an integrator. Reduced SNR and non-linearity resulted because of the integrator’s output swing that is due to change in input. Proposed integrator design significantly increases the SNR. This integrator is designed using 180nm CMOS technology.
Keywords- Sigma-Delta modulator, feed-forward compensation, feedback compensation, operational amplifier.
