PHOTODETECTOR PREAMPLIFIER CIRCUIT HAVING A ROTATING INPUT STAGE

摘要

An amplifier circuit (10) having a rotating front end has a switching network (12) connected to an input (14). A number of parallel transconductance gain stages (16) are connected to the switching network (12). An auto-zeroing circuit (18) is connected to the switching network (12). A second transconductance gain stage (20) is connected to the parallel transconductance gain stages (16).
