An efficiency-enhanced CMOS full-wave rectifier with low dropout voltage is presented. Both the conventional and the proposed rectifiers have been fabricated in a 0.35 mum CMOS process. Experimental results show the output voltage of the proposed rectifier is greater than that of the conventional one. Moreover, the proposed rectifier improves efficiency by more than 10%, compared with the conventional...
The output capacitor and its equivalent series resistance (ESR) often limit the stability of a conventional low dropout regulator (LDR). A CMOS LDR with dynamic zero compensation is presented to tolerate the wide range of the output capacitor and the ESR. The stability constraints for the output capacitor with the ESR are derived. The measured LDR is stable for the output capacitor 2nF-47uF with ESR...
