چکیده
A low voltage square root domain filter based on the MOSFET square law is proposed. Through the verification of HSPICE simulation, the extendibility and the reliability of the design procedure are proven. A design technique for current-mode square-root domain band-pass filter simulation in a 0.18 μm CMOS process. The basic building block consists of current-mode current mirrors, square-root circuit sand capacitors. the prototype of the band-pass provides tunable center frequency of 2.19-3.49MHz with bias-current-tunable, -33.9dB total harmonic distortion(THD), and approximately 1.77 mW power dissipation with a 1.5 V supply voltage. Advantages of the proposed filter include high frequency operation, electrical tuneability, low supply voltage operation, and low power consumption. Keywords— stack technique, square-root domain, band-pass filter, current-mode circuit
