介绍了一种基于双极晶体管跨导线性环路的AB类电流控制接地电阻。仿真结果表明，它的值是可调的，从30到/spl sim/100 k/spl Omega/，频率响应高达100 MHz及以上。在12.5 V电源电压下，总谐波失真（THD）是控制电流值的2.5倍。为了说明它的适用性，一个控制放大器的结果，使用此电阻和电流模式下工作，也给出了。
A class AB current-controlled grounded resistor based on a translinear loop implemented from bipolar transistors is described. Simulation results show that its value is tunable from 30 to /spl sim/100 k/spl Omega/ with frequency responses up to 100 MHz and beyond. With 12.5 V supply voltages, the total harmonic distortion (THD) is 2.5 times the value of the control current. To illustrate its suitability, the results of a controlled amplifier, using this resistor and operating in current-mode, are also given.
