Abstract
This paper presents the construction of a passive uniformly distributed RC (hereafter as URC) device based-on NMOS transistor-only circuits with low phase shift characteristics and high-frequency support similar to the URC. The advantage of the proposed circuit has the variable the resistance-capacitance (RC) or time-constant () of the URC by the voltage control (VC). It to be used in selective-frequency cut-off on better than the normal passive URC, which can't be adjusted. In addition, the proposed circuit uses only a single voltage source to operate at only 2.5 V, resulting in low power consumption. The simulate by PSPICE simulation program was used on TSMC 0.25 um CMOS Technology compared with the passive lump URC to confirm the research results. And simulation results when made the proposed circuit into the low-pass filter and the high-pass filter circuit can be selective-frequency cut-off ranges at 40 kHz-1.6 GHz and 180 kHz-350 MHz by respective.
