R=0.5;//Responsivity in A/W
T=300;//Missing data- Temperature in K
C=1e-12;//Photodiode capacitance in F
BER=1e-6;//Bit error rate
SNR=90;//Signal-to-noise ratio corresponding to BER of (10)^(-6)
kB=1.38e-23;//Boltzmann constant in SI Units
B=100e6;//Bit rate in b/s
Pmin=B/R*sqrt(2*%pi*kB*T*C*SNR);
mprintf("\n For 100 Mb/s, Pmin=%.2f uW",Pmin/1e-6);//Dividing by 10^(-6) to convert into uW
//The answers vary due to round off error
