Circuits Designed by Dave Johnson, P.E. :

Caps Provide Voltage Boost To Series Regulator - This circuit adds some capacitors and diodes to a traditional transformer type series regulator circuit to extend the normal operating range. It can insure regulation during low line voltage conditions or it can squeeze a few more watts out of a plug-in-the-wall power adapter power supply. …
Classic Plus & Minus DC Power Supply - This is a classic example of a regulated DC power supply that produces both a positive 15v and a negative 15v from a 20vac wall adapter….

Buffer adapts single ended signals for differential inputs - 2-Sep-04 Issue of EDN DC coupling of single-ended signals into differential-input, single-supply ADCs can be challenging. The input signal requires level shifting from ground to VS/2 as well as single-ended-to-differential conversion. In addition, you must balance the differential inputs of the ADC to cancel even-order harmonics and common-mode noise.... [Design Idea by Randall Carver, Analog Devices Inc, Greensboro, NC]

Cascode Circuit Lessens DAC Degradation - 02/03/97 EDN-Design Ideas Current-output D/A converters usually deliver their best accuracy if the current-output (summing-junction) pin remains at a constant dc voltage, because of the finite output impedance of the current-out DAC output (Figure 1). Two sources contribute to the output impedance. One is the impedance of the R-2R ladder used to binary-scale the bit currents; the second is the nonlinear output impedance....
