Analog Latch, One-Shot Circuits Operate with Close to Zero Power

Getting serious about power consumption in small, battery-powered wake-up circuits means dropping the clunky old 555s and baling wire in favor of some modern low-voltage analog building blocks. Yes, these same functions can be jury-rigged from AUP logic gates, but the penalty will be high shoot-through supply currents as the gate input voltages hover around the threshold level. The circuits presented here are designed with slow-moving analog signals in mind and don't exhibit that problem.

corrupt file, maybe virus, waste of time if this is what happens when you arrive

I was able to download it without problems. Moreover, the paper is interesting. A couple of years ago I experimented with various solutions to periodically wake up a microcontroller, making sure that they draw less current than using an internal timer. The solutions presented here would do that job pretty well.
