Put in an RC low pass filter with the required RC time constant and frequency response.
Dear anybody! I need to find an appropriate GSM ADCS switched capacitor filters IC. The low pass filter frequency is 300KHZ , switch frequency is 26MHZ. anybody,Plz help me. thanks! Cort-G:D
I am design a switch capacitor circuit. I want to know how to simulate the noise of the circuit. First i want to say the hspice commond (like .noise) is not right for me. I try a low pass filter of SC , then the result of noise simulation is mistake. In the theory , the noise is KT/C, but the figure is not agree with the (...)
