Series-shunt bootstrapping preamplifier circuit for free space optics

The signal level in an optical wireless receiver is weakest at the front-end due to the photo detector capacitance and appropriate design should be done to improve the receiver performance [1]. The optimum receiver performance can be achieved depends on the devices and design techniques used. Thus,...
