The modern medical industry is dependent on electronic devices and systems to accomplish the treatment for various illness in the most efficient manner. To achieve this, accurate diagnosis of the disease/illness is mandatory. This can be done with electronic devices of high accuracy and efficiency. In this project an integrated mixed notch and low pass filter has been identified and its corresponding layout has been designed using complementary metal oxide semiconductor CMOS 180nm technology in cadence virtuoso EDA. In order to achieve a transconductance value of 1nS a bulk driven operational tranconductance amplifier (OTA) has been used with 0.5v supply voltage to design the filters. In this project, a sixth order notch filter and a fourth order low pass filter has been used to achieve high accuracy and reliability of the filters in the bio medical field. This integrated filter using the bulk driven OTA can be employed for multiple systems like ECG,EEG etc. The project focuses on error free layout design of the bulk driven OTA and hence the filters using the bulk driven OTA.
