Title

DESIGNING AN INVERTER-BASED OPERATIONAL TRANSCONDUCTANCE AMPLIFIER-CAPACITOR FILTER WITH LOW POWER CONSUMPTION FOR BIOMEDICAL APPLICATIONS

Pages

  53-59

Abstract

 The operational transconductance amplifier-capacitor (OTA-C) filter is one of the best structures for implementing continuous-time filters. It is particularly important to design a universal OTA-C filter capable of generating the desired filter response via a single structure, thus reducing the filter circuit power consumption as well as noise and the occupied space on the electronic chip. In this study, an inverter-based universal OTA-C filter with very LOW POWER CONSUMPTION and acceptable noise was designed with applications in bioelectric and biomedical equipment for recording BIOMEDICAL SIGNALS. The very LOW POWER CONSUMPTION of the proposed filter was achieved through introducing bias in subthreshold MOSFET transistors. The proposed filter is also capable of simultaneously receiving favorable low-, band-, and high-pass filter responses. The performance of the proposed filter was simulated and analyzed via HSPICE software (level 49) and 180 nm complementary metal-oxide-semiconductor technology. The rate of power consumption and noise obtained from simulations are 7.1 nW and 10.18 nA, respectively, so this filter has reduced noise as well as power consumption. The proposed universal OTA-C filter was designed based on the minimum number of transconductance blocks and an INVERTER CIRCUIT by three transconductance blocks (OTA).
