Circuits Designed by Dave Johnson, P.E. :
[GlobalSpec-AD/ad-smSQ-ihsGS.htm]	Modified LED Night Light - I bought some night lights a few months ago from Walmart here in Denver. The devices were made by Elumina Lighting Technologies Inc. (www. eluminalighting. com) , their model LED-6200A. I think I paid about $15 for a pack of three lights. I wanted a light . . . [Hobby Circuit designed by Dave Johnson P.E., 05/21/07] N-Ch & P-Ch Transistor Form Push-Pull Driver - This circuit can produce high speed output signals with fast rise and full times. The unique change pump action allows the voltage of the upper P-ch device to range from millivolts to hundreds of volts. The output current is only limited by the rating of . . . [Circuit by David Johnson P.E., 06/27/00] Negative 0.5 Volt Supply - This simple circuit consists of two LEDs and a photo diode. It generates a negative voltage with a current level of a couple milliamps. It is ideal for supplying a negative rail to low power “rail to rail” op Amp circuits, which need to have a true zero volts output. Note: This circuit is not particularly efficient . . .

Nine-Volt Battery Voltage Monitor - This circuit turns on a LED whenever the voltage of a standard 9v battery connected to the circuit drops below 7. 2 volts. It uses a LTC1440 comparator, which also contains a 1. 18v reference diode. In standby mode, the circuit draws only 4uA . . . [Circuit by David Johnson P.E., 07/09/06]

Modular Relay System - This is simple transistorised relay into which can be plugged 'personality modules' to turn the base unit into a timer (pulse, delay on energise or delay on de-energise) or a latching relay or whatever is required. This is therefore a universal relay system. It was designed to simplify industrial machinery control. . . . [Page's Author: Richard Torrens]

MOSFET serves as Ultrafast Plate Driver - 10/03/02 EDN Design Idea The circuit in Figure 1 provides a 20-MHz square wave across a set of highly capacitive ion-deflection plates in an experimental instrument. To get the required deflection, the plate voltage must be 20 to 30V, much higher voltage. . . [by Clive Bolton, Bolton Engineering Inc, Melrose, MA]

Motor driver-74*245-based - A simple, time-honored approach is to use one or more 74*245 chips (normally74AC245 is used for maximum current capability) to provide motor drive current. Here, each channel of drive power is provided by one or more buffer onchip. . . . [Wilf Rigter's web site]

MSP430 Interface to TPS60250 via I2C Master Software - LED lighting designers are challenged with meeting their efficiency and reliability goals faster in advanced LED lighting designs. LED lighting customers seeking the latest in innovative and affordable LED lighting solutions can benefit from TI's broad product portfolio of LED drivers, AC/DC, DC/DC, power management devices, wireless and wired interface control and embedded processors. LED designers have the option of not only controlling the power stage, but regulating LED currents as well, eliminating the need for multiple components and reducing system cost. . . .

NiCd Cells Drives Op Amp - 12/05/96 EDN Design Idea . Low-supply-voltage op Amps, such as the LMC6582 and LMC6681 families, feature rail-to-rail I/O with a gain-bandwidth product greater than 1 MHz operating from just 1. 8V. Although impressive, this voltage is not low enough to pow. . . [by Alexander Belousov, Rego Park, NY]
