Solid-State Multiplexers Reduce Half-Bridge Error

By Scott Ellington, January 24, 2000

The half-bridge configuration is handy when using nonlinear sensors, such as thermistors, since it can partially compensate for the sensor's nonlinearity. However, multiplexing a single resistor to multiple sensors generally requires the use of...
20-A Regulator Has Low Drop-Out

By Scott Ellington, February 20, 1992

Taking advantage of the low on-resistance of an n-channel MOSFET (2N3906), this voltage regulator circuit achieves a drop-out voltage of only 700 mV even at currents as high as 20 A.
