Abstract

This paper presents an improved design of current differencing buffered amplifier (CDBA) capable of performing both current mode and voltage mode operations. The improvised flipped voltage follower based current input stage of CDBA offers very low input resistance of only 12.31Ω for considerable frequency range. The voltage follower stage also performs almost rail to rail and exhibits an extremely low output resistance of 3.55 Ω. The circuit is designed in 0.18 µm TSMC technology and the performance of the proposed circuit is examined using H-Spice. The current transfer bandwidth is found to be 67.9 MHz while the Voltage follower bandwidth is 161MHz. The circuit operates at a reasonably low supply voltage of±0.6V while dissipating 0.63mW of power.
