This paper describes a novel bias and gain control circuit for avalanche photodiodes (APDs) biased in linear mode. The circuit was implemented using a printed circuit board (PCB) and packaged APDs. Experimental results show that the circuit is capable of providing bias voltages up to 40 V for the APDs, precisely setting its gain (error < 2.5 %) and… CONTINUE READING
