Michel Meunier, Yves Gagnon, Alain Lacourse, Mathieu Ducharme, Simon Rioux, Yvon Savaria · 2007
A fast, low cost laser trimming technique of highly accurate resistor has been developed for analogue microelectronics. Modelling of the technique is described and an example of tuning a reference voltage circuit is given.
