Every now and then something new comes along that causes you to want to dig down and find out a little more information. Tearing my attention away from Caitlin Jenner for a moment, I thought I'd take a closer look at the remarkable Solar Impulse 2 – an airplane powered solely by solar energy.
Some time back, I had to dig out some ancient filter design tools. I needed a special-purpose digital decimation filter for a “quite high quality” audio communication system.
Sandler has over 30 years of experience in the design and analysis of power conversion equipment for military and space applications.
When analog engineers get together, the discussion always turns technical with a touch of fun. Laptops open up, schematics are surveyed and discussed, good hearty laughter abounds, and fond reminiscing of analog icons no longer with us brings out old stories and some good memories.
It might seem counterintuitive that an active device solution consumes less power than a passive device. Every design engineer knows that a passive crystal resonator (XTAL) doesn’t draw power, so why use an oscillator in place of an XTAL in a power sensitive application? The answer becomes clear when total system power is considered.
