Step of 4 17.086P Refer to Figure 17.36(b) for the integrator in the Redraw the internal circuit with the output resistance and capacitance C. in as shown in figure 1. X + + 1 1 V. sC 0 - - Figure 1 Step of 4 Apply Nodal analysis at X. V. R. sC Therefore the transfer function is is Step of 4 Consider the transfer function 1 Rewrite in time-constant form. Therefore, the integrator time-constant is, Here, T is the time-constant Differentiate partially with respect to C. ac Substitute for 100 Therefore, the smallest value of C that can be used is R. Step of 4 Consider the transfer function Determine the unity-gain frequency V. = 1 + Substitute for Gm 1 + 1 Consider that the low frequency pole is 2 decades lower than 1 20 Therefore, the smallest that the transconductor must have is,
