Abstract

The problem of biasing of high-performance negative amplifiers consists of several issues regarding the values of the DC sources as well as their smart placement. This work is focussed on the second issue. We introduce a graph-manipulating tool that generates an appropriate placement of the bias sources of an amplifier circuit by carrying out a dynamic selection of the pair tree-cotree on the current-stimuli and voltage-stimuli graphs of the circuit.
