EE541 addresses the analysis, design, and implementation of high performance analog filters suitable for data processing, information transmission, and radio frequency (RF) communication systems realized in modern monolithic circuit technologies. Several reasons underlie the necessity of suitable filters in these systems. Foremost among these reasons is that they can be used to match or otherwise modify circuit impedances to ensure the reasonably efficient transfer of signal power between driver and load ports. Maximum power transfer is a critical design objective in high frequency communication networks because the anemic levels of signal power indigenous to such systems increase the risk of contaminating signal information with omnipresent electrical noise. Filters can also be employed to improve the high frequency responses of active circuits by mitigating the deleterious impact of active device capacitances. They can even improve the observable linearity of certain types of active systems by achieving a sharp attenuation of the high frequency harmonics incurred by inherent active device nonlinearities. The RC and RLC filters implicit to electronic power supplies comprise simple examples of filters designed to obviate undesirable harmonics of power line frequencies. Finally, filters can annihilate unwanted signals by offering designable frequency selectivity. For example, low-pass filters all but eliminate undesired signal or noise energy at very high frequencies, bandpass filters offer frequency selective signal processing, as well as a reduction of cumulative output noise energy, and stopband filters obviate the energy of specific frequencies lying within the frequency spectra of signal information earmarked for processing.
