A low-voltage, high-performing CMOS transistor based on multiple- output operation transconductance amplifier for current mode KHN Universal filter applications
Huseyin Demirel
Abstract:This study proposes a current-mode KHN universal filter design that can perform three standard functions simultaneously: low-pass, high-pass, and band-pass. The circuit is built around a multiple-output operation transconductance amplifier (MO-OTA), which allows for electronically adjustable pole frequency and quality factor by modifying input bias currents (IB). The circuit layout is straightforward, with two MO-OTAs and two grounded capacitors, eliminating the need for external resistors and depending entire… Show more
