Abstract

LA TAREA CONSISTE EN REALIZAR UN OSCILADOR DE TECNICA CMOS PARA FRECUENCIAS TANTO MUY BAJAS COMO MUY ALTAS, POR EJEMPLO DE MAS DE 100 MHZ. EL OSCILADOR HA DE SER REGULABLE Y MANTENER CONSTANTES LA TEMPERATURA Y LOS PARAMETROS. EL OSCILADOR CONSTA DE UN POTENCIADOR DE DIFERENCIAL (N5-N12) DE DOS NIVELES Y DE DOS FUENTES DE CORRIENTE REGULABLES (I1, I2). ESTAS FUENTES ESTAN UNIDAS POR UN CONDENSADOR (C) QUE DETERMINA LA FRECUENCIA. AMBAS FUENTES DE CORRIENTE (I1,I2) ESTAN UNIDAS CON LAS ENTRADAS (IN1, IN2) DEL POTENCIADOR DE DIFERENCIAL (N5-N12) A TRAVES DE DOS RESISTENCIAS OHMICAS (R1,R2). LA CAIDA DE TENSION EN LAS RESISTENCIAS (R1, R2) SE OBTIENE POR MEDIO DE UNA UNIDAD DE CONEXION (N1, N2, P1-P4) UNIDA A LAS ENTRADAS DEL POTENCIADOR DE DIFERENCIAL (N5-N12) Y POR MEDIO DE UNA SEGUNDA UNIDAD DE CONEXION (N3,N4)UNIDA A LAS SALIDAS DEL POTENCIADOR DE DIFERENCIAL (N5-N12). CON ESTA CAIDA DE TENSION EL CONDENSADOR (C) ES CAGADO O DESCARGADO. SI ESTA CARGA O DESCARGA SE PRODUCE A TRAVES DE DE LA PRIMERA RESISTENCIA (R1) EL CONDENSADOR OBTIENE UN PRIMER ESTADO DE EQUILIBRIO, SI SE REALIZA A TRAVES DE LA SEGUNDA RESISTENCIA (R2) OBTIENE UN SEGUNDO ESTADO DE EQUILIBRIO
