Description
V(REF)=VRESET−Voff(R1+R2)/R1
となる。ここで、抵抗4,5の抵抗値をR1、R2とした。
V(SIG)=VRESET−Voff(R1+R2)/R1−ΔVdi (R1+R2)/R1
=V(REF) −ΔVdi (R1+R2)/R1
となる。つまり、フォトダイオード1の電位変化を(R1+R2)/R1倍して取り出すことができる。この非反転増幅器の増幅率は、通常2倍から20倍程度に設定する。
V(REF)=VRESET−Voff(C1+C2)/C2
となる。ここで、容量6,7の容量値をC1、C2とした。
V(SIG)=VRESET−Voff(C1+C2)/C2−ΔVdi (C1+C2)/C2
=V(REF) −ΔVdi (C1+C2)/C2
となる。
