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.
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.

Bang Bang Thermostat is Simple and 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. Yet, elementary and crude as servomechanisms are,
examples surround.....(design idea added 10/04)
Better Than Bessel Linear Phase Filters for Data Communications - AN56 Linear
Technology The pace of world of digital communications is increasing at a
tremendous rate. Each day engineer is requested to compact more data in
same channel bandwidth with closer channel spacing. This application note discusses
some of requirements and techniques for using new LTC1064/1164 and
LTC1264-7 filters which were designed specifically....

Component and 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.....(design idea added 6/06)
