Figure 4.32. There is a shorting wire on the left, outside the circuit. It connects the D terminal of a transistor equivalent circuit to the G terminal. The D terminal connects to the bottom line of the circuit and the G terminal is open. There is a current source labeled G sub m V sub gs. Its lower terminal connects to the bottom line of the circuit. The arrow in the current source is pointing up. There is a resistor in parallel with the current source labeled r sub d. Both r and d are lower case. On the right the D terminal connects to the bottom line of the circuit. The S terminal connects to the top end of the current source and the resistor. Outside the circuit a generator connects between the D and S terminals. It is labeled V. Above the S terminal is an arrow pointing to the right and labeled I. End verbal description.
