A linear Gm-cell is proposed and used as a key building block in design of the filter. The linear Gm-cell employs a circuit technique to reduce the nonlinearity of the source follower (SF) stage resulting from unmatched signal swings at the gate and source terminals of the input transistor. The Gm-cell was used to build a biquad bloc, which was utilized to construct a 3rd-order Butterworth low pass filter. The proposed filter consists of a buffer and a biquad stage to form the 3rd-order transfer function. The simulation results of the filter for bandwidth of 10MHz show that the IIP3 of the filter was equal to 29.5 dBm. The minimum in-band noise density was 22.6 nV/√Hz and power consumption was 10.8 mW. The supply voltage of the filter was 1 V. 2019-10-14T14:00:50Z 2019-10-14T14:00:50Z 2019-10 Article International Journal of Nanoelectronics and Materials, vol.12(4), 2019, pages 437-450 1985-5761 (Printed) 1997-4434 (Online) http://dspace.unimap.edu.my:80/xmlui/handle/123456789/62437 en Universiti Malaysia Perlis (UniMAP)
