TLDR
In this article, a negative impedance network of the type which includes a current mirror amplifier having transistors in master and slave paths, a bias current is applied at the commonly connected control electrodes of the master and slaves path transistors, in inverse proportion to the voltage applied across the slave path.Abstract:
Within a negative impedance network of the type which includes a current mirror amplifier having transistors in master and slave paths, a bias current is applied at the commonly connected control electrodes of the master and slave path transistors in inverse proportion to the voltage applied across the slave path and thereby a negative impedance characteristic is derived through the slave path.read more
