Great article with a host of practical circuit suggestions. I can see using this approach on a handheld battery-based instrument used in the field. A solar charging option is a perfect feature when you can't get back to 'base camp'.

It's a simple, elegant approach covered by quite a few papers. If it has a downside, it's that you do need to _know_ what the "maximum power voltage" parameter is for your panel. Maybe this can be acquired in production line calibration. Solar panels are rather variable from batch to batch, so you can't just fit and forget this sort of electronics to an arbitrary panel. The extra complexity of a routine that goes looking for the maximum power point does reduce this concern. but for 'emergency' operation, the last few percentage points of conversion efficiency aren't your main concern.

As data rates begin to move beyond 25 Gbps channels, new problems arise. Getting to 50 Gbps channels might not be possible with the traditional NRZ (2-level) signaling. PAM4 lets data rates double with only a small increase in channel bandwidth by sending two bits per symbol. But, it brings new measurement and analysis problems. Signal integrity sage Ransom Stephens will explain how PAM4 differs from NRZ and what to expect in design, measurement, and signal analysis.
