| Popis: | An efficient low voltage, low input resistance, folded flipped voltage follower current mirror (F-FVFCM) has been proposed. This circuit is further utilized to design very high output resistance, folded cascode flipped voltage follower current mirror (FC-FVFCM). Small signal analysis has been done in order to theoretically analyse and show the improvements achieved by these proposed circuits. Simulations have been carried out by Mentor Graphics based EldoSpice using level 53 TSMC model for 0.18 µm CMOS technology. These results verify that proposed FC-FVFCM offers extremely low input resistance (43.5 Ω), reasonably high output resistance (6.93 MΩ) and very high bandwidth (1.73 GHz) while operating at a low voltage of 0.9 V. |
