Abstract: This research paper presents the design and analysis of two stage CMOS structure with enhanced gain-bandwidth product (GBW) , high slew rate and good phase margin. In this paper, the combined use of negative capacitance and Flipped voltage buffer (FVF) proves quite useful for frequency compensation of MOS amplifiers. This method ensures stability without degrading circuit performance at higher frequencies and is well suited for low power and low voltage analog designs . The use of Negative capacitance lowers the parasitic capacitances of the preceding stage and thereby achieves significant improvement in Gain bandwidth product. The flipped voltage follower acts a voltage buffer and exploits pole –zero cancellation technique. The required compensation capacitor is very small so it can save chip area. The workability of the proposed circuit will be verified by using LT SPICE simulation tool with CMOS 0.18µm process parameters.
Keywords: CMOS , NEGATIVE CAPACITANCE GENERATION, FLIPPED VOLTAGE FOLLOWER
