EFFECTS OF DECISION AMBIGUITY LEVEL ON OPTICAL RECEIVER SENSITIVITY
No full textWe describe the effect of a finite-decision ambiguity level on optical receiver sensitivity. A new analytic expression for the receiver sensitivity including the effect of the decision ambiguity level is obtained by modifying the well-known expression assuming an ideal decision circuit. Also obtained is a requirement for linear channel transimpedance gain or decision ambiguity level for less than 1-dB power penalty of receiver sensitivity

No full textA new type of optical receiver design providing high sensitivity and high dynamic range is presented that employs a lossy noise-matching network and feedback type amplifier. The design is based on the noise figure concept using the four noise parameters of FET, which makes it easy to design multigigabit optical receivers by combining it with microwave CAD tools. The effects of matching network element value and group delay variation of the preamplifier on receiver sensitivities are addressed. The predicted receiver sensitivity including the effect of group delay is 27.1 dBm, which is the highest sensitivity for a 10 Gbit s-1 PIN-FET optical receiver reported to date
Pricing of seasoned equity offers and earnings management
Get PDFThis study examines the relationship between earnings management by firms offering seasoned equity issues and the pricing of their offers. We hypothesize that seasoned equity offering (SEO) firms employing aggressive accounting decisions also more aggressively push up their offer prices, thereby leading to a decrease in the degree of underpricing. Consistent with our prediction (the issuer\u27s greed hypothesis), evidence indicates that SEO firms making opportunistic accounting decisions issue new shares at inflated prices. Our findings remain robust after controlling for other determinants of SEO underpricing and the possible endogeneity of pricing and earnings management
