Abstract
This paper presents a band pass filter and a main amplifier for biomedical applications. Biomedical signals have very low frequency and low amplitude, So signal filtering is a crucial stage in biomedical system and due to very low amplitude of signal amplification is also important stage in the biomedical system. By cascading high pass filter, buffer and low pass filter, Band pass filters designed. The main amplifier is designed by combining two single stage operational amplifiers in parallel. These circuits are designed by Semi-conductor Laboratory 180 nm Technology in Cadence Virtuoso Analog Design Environment. The signal coming from previous stage to filter is the output signal of amplifier stage contains noise and unwanted frequency component, so filtering of signal is important. After filtering of the signal it is sent to the main amplifier stage to provide more gain to low amplitude signal.
