From LTwiki-Wiki for LTspice

I am an electrical engineer and scientist with extensive experience in design of well logging tools, logging while drilling tools, and aircraft environmental controls. My experience in SPICE started with SPICE II simulations of op amp macromodels back around 1980. I have extensive experience with SPICE models of piezoelectric transducers, switching power supplies, RFID antennas, and LWD resistivity tool antennas, and high temperature operation of power MOSFETs and IGBTs.
