  • Blog Post: SPICEing Op Amp Stability

    SPICE is a useful tool to help check for potential circuit stability problems. Here is one simple way to do it: Figure 1 shows a non-inverting amplifier using the OPA211 with a couple of minor variations that are common in many applications. R3-C1 is an input filter. R4 is an output resistor to protect...
  • Blog Post: SPICE It Up! … but does Bob Pease say no?

    August 22, 2012 Anyone who has read a few of my blogs has seen that I simulate circuits in SPICE. You may know that Bob Pease was pretty opinionated about SPICE and once wrote, “SPICE takes away your ability to get good insights on what is happening. Spice actually HURTS your understanding of...
  • Blog Post: Power Supply Bypassing—SPICE Simulations vs. Reality

    Blogging from Wisconsin this week, attending my granddaughter’s second birthday. :) We recently received a question on our precision amplifiers E2E forum with a SPICE simulation schematic attached (thank you for providing a schematic!). It was an op amp circuit—the details aren’t...
