Accelerometer Signal Conditioner - A piezoelectric accelerometer responds to any physical movement by generating a charge proportional to the acceleration of the movement. This sensor has a capacitance of 750pF which produces a charge of 60pC per g of gravitational force. This charge is transferred to the 1000pF feedback capacitor for an output of 60mV/g. __ Linear Technology/Analog Devices App Note, Mar 16, 2010
Piezo Film Sensor Serves as an Accelerometer - Accelerometers are used in instrumentation applications to measure a change in velocity with respect to time or an inclination (the angle between an object’s vertical axis and a line perpendicular to a plane tangent to the earth’s__
Scaling ADXL50 accelerometer output - The ADXL50 accelerometer provides as its output a voltage level which varies in proportion to the amount of acceleration experienced along its sensitive axis. it is calibrated such that under no acceleration the output will be 1.8 volts. Furthermore, an acceleration of 50g (where 1g is the acceleration due to gravity) will cause a voltage swing __ Designed by Tim Stilson

Switched capacitor IC controls feedback loop - 02/17/00 EDN Design Ideas: You can implement a simple control loop with a constant setpoint over a wide range of control by using a switched-capacitor filter. The circuit controls motor speed over 1 to 200 Hz or 60 to 12, 000 rpm. in Figu Design by Dave Sargent, IBM Research, San Jose, CA
Switched-Capacitor IC & Reference Form Elegant –48 to +10V Converter - 04/24/03 EDN Design Ideas: A system designer must almost always face a trade-off in choosing the right part for an application. The trade-off usually involves performance, price, and function. An example is the issue of powering circuits from a telecom-voltage source. Telecom systems almost exclusively use high-potential negative rails, such as -48V Design by Wallace Ly, National Semiconductor, Santa Clara, CA
Switched-capacitor converter suits portable applications - 08/17/00 EDN Design Ideas: Basic switched converters generally provide one simple voltage conversion. The most common application for these circuits are to double, invert, and sometimes halve the input voltage. Because they are unregulated and have no stability problems, you can configure them to perform multiple conversions as well. Design by Clinton Jensen, National Semiconductor, Santa Clara, CA
