Abstract

This chapter presents the design of a second-order switched-current delta-sigma modulator having equal first and second integrator output swing. It was implemented using the clock-feedthrough compensated first-generation switched-current circuits described in chapter 4. Experimental results show that the modulator has a small chip area, low supply voltage, and low power dissipation. The measured dynamic range is approximately 11 bits.
