A student is characterizing a pn junction by measuring its capacitance CJ (v) 5 CJ0y(1 2 vy 0 ) m at different junction voltages v. If it is found that Cj (0) 5 10 pF, Cj (22 V) 5 6.87 pF, and Cj (28...

A student is characterizing a pn junction by measuring its capacitance CJ (v) 5 CJ0y(1 2 vy 0 ) m at different junction voltages v. If it is found that Cj (0) 5 10 pF, Cj (22 V) 5 6.87 pF, and Cj (28 V) 5.4 pF, estimate the values of Cj0, 0, and m. Hint: you may fi nd it convenient to express the above relation in the form mlog(1 2 vy 0 ) 5 log( Cj0 y Cj ). Is this junction of the abrupt or of the graded type?
