What are the different types of capacitance seen in PN junction diode ? Briefly explain about junction capacitance. Find the junction capacitance of a Si p-n junction at T = 300K with doping concentration of Na=10^17 /cm³ in p-side and Nd = 10^15/cm³ in n-side. Assume ni=1.5x10^10 /cm³ and reverse bias voltage V_{r} = 5V . Assume cross sectional area of junction is 10^-4cm². Given Es= 11.8 Eo, Eo = 8.85x10^-14F/cm
