Abstract

PARA REALIZAR UN CIRCUITO DE PUESTA EN MARCHA AUTOMATICA, SE CONSTITUYE UN ESPEJO DE CORRIENTE EN LAS RAMAS DEL CUAL SE COLOCA EN CASCADA CELULAS DOTADAS DE UN TRANSISTOR DE DETECCION DE REJILLA FLOTANTE. SE CARGAN LAS REJILLAS FLOTANTES DE ESTOS TRANSISTORES DE UNA MANERA DIFERENTE DE MANERA QUE EL CIRCUITO REACCIONE EN FUNCION DEL VALOR DE LA DIFERENCIA DE ESTAS CARGAS. SE MUESTRA ENTONCES QUE ESTA REACCION ES INDEPENDIENTE, POR UNA PARTE DEL PROCESO DE FABRICACION DEL CIRCUITO INTEGRADO, Y POR OTRA PARTE DE LAS CONDICIONES DE FUNCIONAMIENTO EN TEMPERATURA O EN TENSION DE ALIMENTACION. ESTE DISPOSITIVO ES MAS PARTICULARMENTE APLICABLE AL CAMPO DE LAS TARJETAS DE MICROCHIP.
