EE 230 HW 9 Spring 2010 Problem 1 Determine analytically and plot the transfer characteristics of the following circuit if the Nonlinear Device (NLD) can be modeled with the I-V characteristics > = = 0 0 V 0 0 D D D D I for V for I . The transfer characteristics of the NLD are shown below. 20K NLD 5K 2K V IN V OUT NLD V D I D I D V D Problem 2 Repeat the previous problem if the nonlinear device orientation is reversed as show. 20K 5K V IN V OUT NLD 2K Problem 3 Assume the nonlinear devices, denoted as D 1 and D 2 , can be modeled as shown below. a) Obtain an expression for and plot the transfer characteristics of the following comparator
