Improved FGMOS-Based Low-Voltage Voltage Follower

Abstract

The use of floating-gate MOSFETs (FGMOS) in designing low-voltage analog circuits is presented. A FGMOS based low-voltage voltage follower and its use in CCII structures is presented. Working of such CCII structures is ascertained by using them in current-mode and voltage-mode band-pass simulated filters.

Indexing terms:

• Floating gate MOSFET
• Voltage follower
• Current conveyor
• Active filters
