Many analog signal-chain circuits require ac-coupling to eliminate unwanted dc voltages or offsets. The simplest means to ac-couple is to use a capacitor in series with the signal path, thus forming a ...
How programmable RF filters offer user flexibility. The basic capabilities and setup requirements of this MMIC GHz-band filter How an evaluation board can simplify user comfort level and speed design ...
In Part 1 (click here), we learned how an old technique known as servo feedback can remove dc offsets in a dc-coupled gain block, without putting any components, especially capacitors, in the ...
