Signals in the real world contain both its wanted and unwanted information. All electronic design projects gives off signals that require electronic signal filtering, processing or amplification, from the simple gain up until to the very complex digital-signal processing. This is the main importance of electronic filters to remove the unwanted frequency components from the signal and to enhance the wanted frequency components to produce an output with lesser noise. The thesis project will be a fourth order low pass switched-capacitor. The proposed design will result to a tunable low pass output integrated in a single circuit. The target signal-to-noise (SNR) ratio will be 60dB and its operating frequency will range from 0Hz-30 kHz having a clock frequency ranging from 10Hz - 1.2 MHz. Also, the considered slew rate for this project will be rated as 3 volts per microsecond. The group will be using Tanner 0.25 micron CMOS technology for its implementation.
