振荡器模拟知识讲座(pdf 16页)

About this lab exercise: This lab exercise is in two parts:
Part 1: You use a prebuilt example oscillator file and perform one simulation.
Part 2: You build an VHF VCO and preform several simulations.
OBJECTIVES
· Use OscTest Element to get frequency and S-parameter information.
· Build an oscillator and simulate numerous performance tests.
PART 1: PROCEDURE – Oscillator Example
1. Create a new project named: oscillator
2. Copy the example design into your directory
From the Main window, use the Copy Design command. When the dialog
box appears, browse the example directory and copy from:
examples \ tutorial \ LearnOSC_prj \ networks \ Osctest_VCO.
To Path: oscillator_prj \ networks\
3. Open the new oscillator schematic design
a. Zoom in on the device and notice that it has two emitters. You can
remove the pin labels in the Pin/Tee tab of the Options>Preferences
dialog. Notice that the unconnected emitter is showing red
(unconnected pin) – this is OK.……
