High-frequency switched-capacitor filter using unity-gain buffers |
| |
Abstract: | The implementation of high-frequency switched-capacitor filters using unity-gain amplifiers in a balanced configuration is described. The effect of parasitic capacitances is analyzed for different structures, single-ended and balanced. Experimental results from a third-order elliptic filter integrated in a standard NMOS process are presented. |
