Abstract
A current switching system is described. This system includes first and second mirrored devices coupled to each other and a coupled terminal, and the first and second mirrored devices are coupled to an input terminal and an output terminal; a storage element in element in parallel with the first mirrored device and the first degeneration device; a variable impedance device coupled between the coupled terminal and a low voltage device; and a current mirroring accuracy enhancing circuit coupled between the coupled terminal and a high voltage device, wherein the variable impedance device dynamically changes a current at the coupled terminal to a second level depending when a threshold is met, and an impedance on the coupled terminal remains low both before switching and during switching.
