<azonenberg> Ordered a bunch of parts for a new probe design, tentatively to be called the AKL-AV1
<azonenberg> Single ended high impedance active probe targeting around 3 GHz bandwidth
<azonenberg> I ordered some BUF802s a while ago with this in mind
<azonenberg> but now have the preliminary power supply components picked out
<azonenberg> It will use a LTC1983 charge pump to produce a -5V rail from a +6V input rail
<azonenberg> then ADP7142 and ADP7182 positive and negative LDOs to produce +/- 4.5V from that
<azonenberg> Which will then run the BUF802
<azonenberg> It will be a solder in probe in the same basic form factor as the AKL-PT5, but without a tip resistor - just two tiny wire leads
<d1b2> <azonenberg> Actually on second thought
<azonenberg> I think a tip resistor would work. and i can combine with a capacitive dropper similar to a normal 10x scope probe
<azonenberg> but with much lower C
<azonenberg> This would also reduce the effective loading as seen by the DUT even less than the raw BUF802 input would
