Electrical Engineering

An 8-bit A/D Converter on a chip using 0.18um technology with aVdd=1.8V is built using minimum size transistors (l=0.18um andw=0.36um). It has 22 transistors per bit in conversion and 128transistors used for memory. The activity factor in the conversionmodules is 0.1, while the activity factor in the memory blocks is0.02. Assume each transistor contributes 3fF/um of gate capacitanceand 0.24fF/um of diffusion capacitance. Estimate the switchingpower without capacitance when operating at 1MHz.
