For a system with G(s) in forward path and H(s) in feedback path, Derive in details the equivalent transfer function and its zeros/poles?

With the advent of capacitive touch sensors the human body capacitance has an ever incresing role to play in the design of touch screens, switches etc. Besides ESD (electrostatic discharge ) from and to the human body from various electronics devices and gadgets is important for EMC (electromagnetic compatibility) of the gadgets. Your assignment is to estimate the range of human body capacitance. Give detailed justification for your method of estimation. Compare your estimates to available/published data sheets.

Write the Pros and cons of the second and third generation of the solar photovoltaic cells.

For a particular DRAM design the cell capacitance is C,=50fF, Vpp=5 V and V=1.4 V. Each cell represents a capacitive load on the bit line of 2fF. The sense amplifier and other circuitry attached to the bit line has a 20fF. What is the maximum number of cells that can be attached to a bit line while ensuring a minimum bit line signal of 0.1 V? How many bits of row addressing can be used? If the sense amplifier gain is increased by a factor of 5 how many word line address bits can be accommodated.
