Using Symbolic SPICE® to solve various circuit and electronics problems is sometimes very different than solving a numerical problem. The Applications Notes below are a collection of practical problems that were solved using Symbolic SPICE. In many cases, these problems were solved using only the Demo Version of the program.
AN-001: Series Resonant Circuit
AN-002: Treble Tone Control
AN-003: Notch Filter Using a Simulated Inductor
AN-004: An Op-Amp Phase Shift Oscillator
AN-005: An Op-Amp Wien Bridge Oscillator
AN-006: Magnetic Microphone Amplifier
AN-007: Approximating the Bandwidth of the Mic Amp
AN-008: GBP Effects in a MFB Band-Pass Active Filter
AN-009: Approx. Gains in a Two-Stage CMOS Op-Amp
