Abstract
A class AB current-controlled grounded resistor based on a translinear loop implemented from bipolar transistors is described. Simulation re sults show that its value is tunable from 30 to similar to 100k Ohm wi th frequency responses up to 100MHz and beyond. With 12.5V supply volt ages, the total harmonic distortion (THD) is < 1% for peak to peak mag nitudes of the input current > 2.5 times the value of the control curr ent. To illustrate its suitability, the results of a controlled amplif ier, using this resistor and operating in current-mode, are also given .
