The goal of this work is to design a best in class, wide bandwidth (>8GHz) wide dynamic range (>60dB) log amp power detector for wireless base station or RADAR applications. Power consumption is an important performance metric. In addition, temperature compensation networks that allow the design to maintain an output variation versus temperature that is 2 dB or less are developed. Because this circuit may be used as a reference in a feedback loop, provisions for trimming the output in order to minimize part to part variation are included. The supply voltage used for the trimming process may differ from that used in the final application, therefore an on board power management scheme is provided in order to maintain the proper trimmed response at the point of use. Ultimately this work must produce a production worthy design, so ESD networks are included, latch up and antenna damage issues are eliminated, and yield is considered.
