The figure shows the automatic gain control shift amplifier circuit. This circuit consists of four parts: The amplification unit circuit gain programmable instrument (with amplification integrated chips PGA202 component). It adds and subtracts counter unit, two-way comparator unit and 10 V benchmark voltage source. The internal structure of PGA202 is shown in figure (b), its gain can be controlled by TTL level, the integrated chips and single-chip microcomputer are easily interfaced. The PGA202 for mosfet input type and includes the conductive road, it can realize across the bandwidth in different gain almost the same.
