0.5V Low Power Level Shifter Flipped Source Follower LPF Circuit for Healthcare System

A high-cut filter design, which is considered an important circuit can be used to provide significant advantages in the implementations of biological systems. This paper, presents a LSFSF LPF planned for biological healthcare systems. The LSFSF LPF design has been pretend in CMOS $0.18 \mu \mathrm{m}$ technology node. The proposed LPF gives -3 dB of gain, 100 Hz of bandwidth, 1 nW of power, $83 \mu \mathrm{V} _{rms}$ of IRN and $0.5 \times 10^{-13}$ J of figure of merit. The demonstrated LPF design can be used to achieve low-power dissipation and low-energy operation in biological health care systems.
