Designing with ultra-low voltage MOSFET arrays
Design How-To 8/31/2005 Post a comment
Using a floating gate charge, Advanced Linear Devices has perfected a way of programming the threshold voltages of MOSFET arrays. With something close to a zero-volt threshold, MOSFET switches can be turned one-or-off with a hare's breath of power. But this will force designers of portable circuits to think differently about the design of their amplifiers, voltage references and current mirrors, suggests developer Robert Chao. This article offers some insights and suggestions.
