Note in the equivalent circuit of Fig. 16.45 that the capacitor appears in parallel with the negative resistance. Determine the reactance of the capacitor at 1 MHz and 100 MHz if C = 5 pF, and determine the total impedance of the parallel combination (with R = –152 Ω) at each frequency. Is the magnitude of the inductive reactance anything to be overly concerned about at either of these frequencies if L_S = 6 nH?
