Analog input circuit Serves any microController - 12/20/01 EDN-Design
Ideas: The simple ADC in Figure 1 is perfect for getting analog signals
into a purely digital microcontroller. Using just five surface-mount
parts, you can assemble it for less than 50 cents (1000) , which is
approximately half cost of a single-chip- ADC approach in
same volume. Moreover, this design takes only one pin from
microcontroller to operate.....(design idea) |

Bias Voltage & Current Sense Circuits for Avalanche Photodiodes -
AN92 Linear Technology Avalanche photodiodes, used in laser based
fiberoptic systems, require high voltage bias and accurate, wide range
current monitoring. Bias voltage varies from 15V-90V and current ranges
from 100nA to 1mA, a 10,000:1 dynamic range. This publication presents
various 5 volt powered circuits which meet se requirements. Appended
sections detail specific circuit techniques and cover measurement
practice. |

AC Current Indicator Light - This circuit could be wired into a
120vac power line, which feeds power to any load, ranging from 40 watts
to 250 watts. It will turn on a LED light whenever current is being
drawn by a load. It is especially useful for remote lights, where you
may not be able to see if the lamps are receiving power. ….(designed by
David A. Johnson) |

AC Line Current Detector - This circuit will detect AC line currents
of about 250 mA or more without making any electrical connections to the
line. Current is detected by passing one of the AC lines through an
inductive pickup (L1) made with a 1 inch diameter U-bolt wound with 800
turns of #30, #35 magnet wire. The pickup could be made from other iron
type rings or...(electronic schematic / circuit) |

designer with some significant challenges. Most techniques for sensing
current involve measuring differential voltage current produces as it
flows through.....(design idea) |
