Parametric Analysis of a Novel Dual-Output Current-Mode Filter for VHF/SHF Band Utilization

Numerous research work in the field of analog filters has already been done and researchers have reached a place where robust low-power miniaturized integrated circuits are of utmost demand in the area of wireless communication. Almost all kind of filter functions are required in any RF communication, and therefore, a novel current-mode, fine-tuneable, 9 MOSFET-based Dual-output filter circuit is proposed for low-pass and band-pass output for a sine wave of amplitude 10 μA and a frequency of 60 MHz. AC and transient analysis of the proposed circuit are carried out to show the filter circuit’s behavior. The AC and transient response of the proposed filter with least MOS count is thoroughly investigated. The operating frequency is in the range of a few GHz, which covers the wireless world applications, especially in UHF and SHF bands such as mobile communications in 4G/5G networks, aeronautical mobile, Bluetooth, Wi-Fi, fixed (both one-to-one and one-to-many), radio-astronomy, and meteorological-satellite services etc.
