    “Trust, but verify” SPICE model accuracy, part 4: open-loop output impedance and small-signal overshoot

    Previous installments of this blog post series discussed the need for verifying SPICE model accuracy and showed how to measure common-mode rejection ratio (CMRR), offset voltage versus common-mode voltage (Vos vs. Vcm) and slew rate (SR). In part four, I’ll continue putting operational amplifier (op amp) SPICE models to the test by checking their...

    Forget the tiny homes craze – Have you heard about tiny inductors for automotive Class-D amplifiers?

    You can’t turn on the TV or open a website lately without seeing or reading about the tiny home craze. Smaller is supposedly better, right? Similarly, mobile phone manufacturers tout how small, slim or lightweight their next-generation phone is. It just seems natural that this trend would spill over into the automotive audio Class-D amplifier...

    Unique active mux capability combines buffer and switch into one solution

    This post is co-authored by Anthony Vaughan . Designers often run into the problem of selecting one of two (or several) inputs to pass on to the next stage. While a plethora of multiplexer (mux)-type devices use a modified impedance approach to select which input passes to a single output, a new high-speed precision operational amplifier (op amp...
