Description
This paper quantitatively analyses the relation between the return of private
seasoned equity offerings and variables of market and firm characteristics in China Ashare
market. A multiple-factor linear regression model is constructed to estimate this
relation and the result canhelp investors to determine the future return of private
placement stocks.
In this paper, I first review past theories about private placement stocks, including how
the large shareholder participation, the discount of private offerings, the firm
characteristics, and the investment on firm value will affect the return of private
offerings.
According to the past literature, I propose four main factors that may affect the
return of private placement. They are the large shareholders participation in private
placement; the discount that private placement could offer; the characteristics of the
companies that offer a private placement and the intrinsic value of such companies. I
adopt statistic and correlational analysis to test the impact of each factor. Then,
according to this single-factor analysis, I set up a multiple-factor linear regression model
on private seasoned equity offerings return in Chapter Four.
In the last two chapters, I apply this quantitative model to other fields. I use this
model to testify current financial products of private placement and develop investmen
strategies on stocks with private seasoned equity offerings in secondary market. My
quantitative strategy is useful according to the result of setback test.

Description
Readout Integrated Circuits(ROICs) are important components of infrared(IR) imag
ing systems. Performance of ROICs affect the quality of images obtained from IR
imaging systems. Contemporary infrared imaging applications demand ROICs that
can support large dynamic range, high frame rate, high output data rate, at low
cost, size and power. Some of these applications are military surveillance, remote
sensing in space and earth science missions and medical diagnosis. This work focuses
on developing a ROIC unit cell prototype for National Aeronautics and Space Ad
ministration(NASA), Jet Propulsion Laboratory’s(JPL’s) space applications. These
space applications also demand high sensitivity, longer integration times(large well
capacity), wide operating temperature range, wide input current range and immunity
to radiation events such as Single Event Latchup(SEL).
This work proposes a digital ROIC(DROIC) unit cell prototype of 30ux30u size,
to be used mainly with NASA JPL’s High Operating Temperature Barrier Infrared
Detectors(HOT BIRDs). Current state of the art DROICs achieve a dynamic range
of 16 bits using advanced 65-90nm CMOS processes which adds a lot of cost overhead.
The DROIC pixel proposed in this work uses a low cost 180nm CMOS process and
supports a dynamic range of 20 bits operating at a low frame rate of 100 frames per
second(fps), and a dynamic range of 12 bits operating at a high frame rate of 5kfps.
The total electron well capacity of this DROIC pixel is 1.27 billion electrons, enabling
integration times as long as 10ms, to achieve better dynamic range. The DROIC unit
cell uses an in-pixel 12-bit coarse ADC and an external 8-bit DAC based fine ADC.
The proposed DROIC uses layout techniques that make it immune to radiation up to
300krad(Si) of total ionizing dose(TID) and single event latch-up(SEL). It also has a
wide input current range from 10pA to 1uA and supports detectors operating from
Short-wave infrared (SWIR) to longwave infrared (LWIR) regions.
