摘要：
This paper will describe the design of a general purpose continuous-time IF analog filter that utilizes log-domain integrator circuits. The coefficients of the filter are digitally programmable and externally controlled using a serial input data stream. Both the poles and the zeros of the filter are adjustable, allowing arbitrary filter function implementation. The filter has been fabricated in a 0.8 micron BiCMOS technology and it is capable of 2.5 volt operation. The experimental results are included.
