Hi,
I just finished building a mic with Dale's C-37 capsule. As I thought it would be, the noise floor is too high without a DC-DC converter.
I've been messing around with a 74C14 CMOS Logic Hex Schmitt Trigger. I can get it to multiply the voltage, but I can't seem to get the current draw low enough. I know others have already posted some about this. I've read these posts but I'm still stuck. Just so you know, I did ground the input of all unused gates on the inverter.
Is there anyone who might have some pointers for me?
Thanks!
