Question 15.2: TRANSFER FUNCTION ANALYSIS OF A CIRCUIT WITH A NEGATIVE RESI...
TRANSFER FUNCTION ANALYSIS OF A CIRCUIT WITH A NEGATIVE RESISTOR
A circuit with negative components is shown in Figure 15.5. The input voltage is V_{in}= 120 V (peak), 60 Hz. Use PSpice to calculate the currents I(R1), I(R2), and I(R3) and the voltage V(2).
The PSpice schematic with a negative resistance is shown in Figure 15.6.
The listing of the circuit file is as follows:
