Circuits Designed by Dave Johnson, P.E. :

Circuit forms Divide by 1.5 Counter - Two inexpensive ICs divide a TTL clock signal by 1.5. By following the circuit with another flip/flop, you could also generate a divide by three function.....
CMOS Inverter Makes Low Power Amp - With the addition of one resistor and a capacitor, some common logic ICs can be transformed from digital to analog duties. This circuit outlines some the features to expect from different inverter ICs. ….

Bang Bang Thermostat is Simple & Efficient - 11/06/97 EDN-Design Ideas.....Perhaps simplest and oldest feedback loop is nonproportional, all-or-nothing, "bang-bang" rmostat. Fully turning on a heater when temperature is below setpoint and off when it's above setpoint is a straightforward example of a servomechanism. .....

Component & Measurement Advances Ensure 16-Bit DAC Settling Time - AN74 Linear Technology DAC DC specifications are relatively easy to verify. AC specifications require more sophisticated approaches to produce reliable information. In particular, the settling time of the DAC and its output amplifier is extraordinarily difficult to determine to 16-bit resolution. This application note presents methods for 16-bit DAC settling time measurement.....

Convert binary data to BCD in just 92 µsec - 05/21/98 EDN-Design Ideas.....The subroutine "FASTBCD" (Listing 1]for 8051 µPs quickly converts 16-bit binary to 24-bit BCD data. The conversion algorithm involves left-shifting bits from the high-order bit of the binary number into the carry bit while left-shifting the carry bits into the low-order bit of a BCD shift register using BCD left-shift operations.....
