Just How Fast is GaN Fast?
By Steve Sandler | March 12, 2020
“I recently designed an ultra-high speed, low-impedance pulse generator (Figure 1). I wanted it for evaluating oscilloscope probe performance ,  and for determining the feasibility of an in-socket load for ASIC emulation. The obvious choice, due to size and desired performance, was an eGaN FET. One of the devices I used is an EPC2037, 0.9 mm device. As it turns out, the hard part wasn’t designing the pulser, but determining just how fast the pulse is and whether the pulse itself introduces ringing. In case I didn’t mention it, the eGaN device is also a flip chip, so there is no access to the device solder bumps once it’s installed…” Click here to read the entire article
