Application of High Pass Filter in Robotics: A Circuit Perspective

Abstract

Electronic robotic system has a section of transmitter and receiver. For the receiver, to provide the required selectivity of frequencies, a filter is used. There is a wide variety of these filters that can be used within the Radio Frequency (RF) range. Radio frequencies range from 3 kHz to 300 GHz. This work analyzes the steps involved in the design and simulation of a 100 GHz (0.1 THz) third order active high pass filter. This filter uses the operational amplifier for the first stage and transistor for the further stage. By cascading these two stages a third order filter is designed. Using this model of filter a fine signal (command) can be given to robotic system.
