Abstract

Circuito amplificador de transimpedancia integrado, que ofrece la posibilidad de ajustar la ganancia y el ancho de banda, y de añadir módulos externos de control automático de ganancia (CAG) y de control de nivel de salida, estando el circuito destinado a amplificar la fotocorriente generada por un fotorreceptor en receptores de sistemas de comunicación por fibra óptica, y que comprende una primera etapa (1) preamplificadora de transimpedancia con una estructura cascodo modificada, doblemente realimentada, que permite el control sobre el producto ganancia por ancho de banda mediante un terminal (5), y disponiendo a su salida de un terminal (6) de monitor con la referencia del nivel de señal recibida. Una segunda etapa presenta un amplificador (2) de ganancia variable, con una entrada para CAG externo, y una tercera etapa la constituye un buffer (3) de salida con una entrada para el control de nivel de salida externo. **FIGURA**
