A New High Performance Active Building Block Suitable for Low Voltage Low Power Signal Processing

Abstract: In this research paper, a novel low-voltage low-power current follower differential input transconductance amplifier (CFDITA) based on floating gate MOS is presented. The proposed CFDITA has an important feature of electronic controllability with the help of bias current. Moreover, this design is realized with both PMOS and NMOS current mirror structures using floating gate technique. So, another important feature of the design is that it operates in bilateral mode. It is designed at a supply voltage of ± 0.75V and consumes a power of 0.8 mW at 100 μA bias current. All the results provided to verify the device performance are simulated using SPICE with 0.18 μm CMOS technology process parameters. The simulation results confirm the theoretical concepts.
