Impedance Matching Figure 4.11 Lowpass and highpass matching network for Example 4.4. Figure 4.12 Frequency response for lowpass and highpass matching networks. Example 4.4 The Effect of Matching on Noise Study the impact of matching on base shot noise. Use the 15x transistor defined in Table 3.1, which is operated at 2 mA at 1 GHz. Solution The small-signal model and calculated matching impedances are shown in Figure 4.14. The transistor has an input impedance of 1,250� in parallel with 700 fF, which at 1 GHz is equal to Z� = 40 − j220�. Using this and the base resistance of 5�, the impedance seen by the base shot noise source can be 73

Figure 4.14 Calculation of impact of impedance matching on base shot noise. determined. Without matching, the input is driven by 50�, so the base shot noise sees 55� in parallel with 40 − j220�, which is equal to about 50 − j11.6�. With matching, the base shot noise sees 50 + j220� in parallel with 40 − j220� for a net impedance of 560 − j24�. Thus, with matching, the base shot noise current sees an impedance whose magnitude is about 10 times higher, and thus the impact of the base shot noise is significantly worse with impedance matching. 4.4 Conversions Between Series and Parallel Resistor- Inductor and Resistor-Capacitor Circuits Series and parallel resistor-capacitor (RC) and resistor-inductor (RL) networks are widely used basic building blocks of matching networks [1, 2].
