  • Milli-Ohm Meter - Jim Williams Application Note

    Created by SouthPacific, published on 04-04-2015

    Jim Williams - Linear Technology - Application Note - AN98 page 10/11 Using Synchronous Demodulation techniques, the circuit pulses current into the resistance-under-test. It then synchronously detects the result and amplifies it.

  • Dynamic Load Circuit Determines a Battery's Internal Resistance

    Created by SouthPacific, published on 04-04-2015

    Jim Williams - Linear Technology - Design Idea EDN March 31, 2005 The circuit is used to measure a battery's internal resistance by synchronously loading and unloading the battery terminals at a slow rate. The measured difference voltage gets amplified to indicate the batteries Internal Resistance.

  • Accelerometer with Operational Amplifier

    Created by LTspiceDesigner, published on 02-12-2014

    SPICE simulation of a shock sensor amplifier (accelerometer) implemented with a LTC6081. A capacitive piezoelectric element provides a charge under physical acceleration. The charge is converted to a voltage and filtered by the high impedance of the operational amplifier. The gain is 100, the bandwidth about 2.2khz and the output generates 109mV per g of acceleration.
