Abstract :
A systematic method for designing broadband delta-sigma modulators will be described. In particular, the design of a delta-sigma modulator in a 0.18 μm CMOS process achieving a 13-bit resolution over a 1 MHz bandwidth is presented. Circuit non-idealities in the main building blocks are modeled in Simulink/Matlab® allowing one to optimize the design for power, bandwidth and resolution. Methods for enhancing the speed of optimization will be described.
