Switched filter
SpletA novel technique for building active filters using switched-capacitor (SC) circuits is proposed. Principles of operation, methods of control, analysis, and design of a typical … SpletAlmost every switched-mode power supply (SMPS) needs an EMI (Electro Magnetic Interference) input filter to suppress any disturbances of the SMPS on the power lines. This requirement having an input filter in the design ensures that no negative effect will occur in other parts of the systems connected to the power lines.

SpletThe filter design uses a fully differential class A/B op amp with a continuous-time common-mode feedback circuit. Distortion measurements show that for 82-dB dynamic range (relative to noise floor) the total harmonic distortion of 0.02% within the whole 4-kHz bandwidth and 0.07% within 20-kHz bandwidth. The simplest switched-capacitor (SC) circuit is made of one capacitor and two switches S1 and S2 which alternatively connect the capacitor to either in or out at a switching frequency of . Recall that Ohm's law can express the relationship between voltage, current, and resistance as:
