what happens when you pair an ADC designer with a PA designer?
The SCPA was invented by Dr. Sangmin Yoo and Dr. Jeff Walling while working with Prof. David Allstot at the University of Washington
Here is the first
A 90nm CMOS die with a single-channel 6b SCPA on the left and a transformer power-combined SCPA on the right. The trasnformer combined PA was the first to incorporate both parallel and sequential driving of the transformer windings.
