Comparator Design for Delta Sigma Modulator
In wide band communication systems, low power and high speed ADCs forms the main building blocks. These ADCs are commonly seen in the front end of the radio frequency receivers. Comparators are used in these ADCs. A CMOS Comparator design, based on amplifier-push pull inverter circuit is elaborated in this paper, which is intended to be used as the 1-bit ADC required for the implementation of a...

متن کاملA Comparator-Based Switched-Capacitor Delta Sigma Modulator
Comparator-Based Switched-Capacitor (CBSC) is a relatively new topology that replaces opamps in sampled-data systems with a comparator and a set of current mirrors. CBSC is expected to lower power consumption, and to avoid several delicate tradeoffs of op-amp circuits. In this paper, the original single-ended CBSC block is extended to a fully differential version. The differential CBSC is then ...

متن کاملA Low Power Audio Delta-Sigma Modulator with Opamp-Shared and Opamp-Switched Techniques
A high power efficient opamp-shared and opamp-switched delta-sigma modulator (DSM) has been presented. It employs a fourth-order single loop 17-level DSM with an input feed forward gain stage. It is shown that power consumption can be largely reduced by using half delay integrators and switched opamp, and sharing opamp between integrator stages. The proposed DSM, designed on 0.35μm TSMC process...
