Abstract

Design and measurement of root-mean-square detector based on triple-tail cell is described. Triple-tail cell is a low-voltage operating squaring Circuit. We investlgated to use the triple-tail cell as an rms detector for RF signals. The most crucial problem ith this attempt may be how to cancel out large offset current component which carrylng rms signal of the input. Several offset ancellation circuits are proposed based on current-mirror circuit. Simulation study was made on these circuits and the best circuit as bread boarded by using discrete component. Measured result shows that 20 to 30 dB of input range of 1-dB deviation from ideal square law.
