• Journey to the Center of the Scope - How an Oscilloscope Works

    The second the probe is connected to your device your signal begins a grand journey to the center of the scope. It has to pass through five phases in order to complete its journey to the center, then back up to the su...

  • Oscilloscope Triggering: When is Normal not so Normal?

    Oscilloscopes have two primary modes of triggering: AUTO and NORMAL. However, NORMAL is not the normally used mode of triggering. AUTO is. The default trigger mode in all of today’s oscilloscopes is AUTO. There ...

  • Creating Verilog-A Models in ADS from VHDL-A Code: Part 4 - Derivatives

    In Part 1 we only translated a simple resistor. Let's look at a more complicated model, a diode with a junction capacitance that varies with voltage. Here is the model in VHDL-A, keywords in bold: library IEEE, ...

  • Creating Verilog-A Models in ADS from VHDL-A Code: Part 5 - Verification

    When you create a Verilog-A version of a VHDL analog model, you'll want to verify that the two match. A convenient way to do this is to compare things like I-V curves, for example. The ADS simulator can place data for...
