Abstract :
A voltage-controlled logarithmic attenuator is presented that may be stabilized by the use of dc degeneration and a suitable increase in loop gain. The stabilized attenuator may be designed as either a high- or low-impedance device. A design procedure is outlined for each case. A discussion of experimental results concludes the paper.
