Instrumentation Amp makes noninverting integrator -  09/19/02 EDN-Design Ideas Figure 1a shows the classic implementation of an integrator.  The circuit has two properties that may be undesirable in same applications  It necessarily inverts, and it requires a split-supply or midsupply reference.  Figure 1b shows an implementation of an integrator that uses an LT1789 instrumentation amplifier__ Circuit Design by Glen Brisebois, Linear Technology Corp, Milpitas, CA

Integrator forms picoammeter -  07/17/97 EDN-Design Ideas The analog circuitry necessary to precisely resolve picoamperes can challenge even the best designer.  At these minute current levels, noisy and nonreproducible circuit topologies are common.  A current-to-voltage (I/V) converter that uses an op amp and large feedback resistor is the obvious first design choice to acquire a small current.  However, the component errors that this method induces can swamp the measurable current (and can amount to throwing out the baby with the bath water).  __ Circuit Design by Clayton B Grantham, Burr-Brown Corp, Tucson, AZ

Inverting Switched Capacitor Integrator -  Circuit Ideas for Designers App Note___ Advanced Linear Devices, Inc

Opamp Integrator -  The integrator basically works like this: whatever current I you get flowing in R1, gets integrated across capacitor C1.  The output voltage Vo is simply the voltage across C1.  One great application of the integrator is generating a ramp voltage.  You can do this by placing a fixed voltage __

Precision Charge Integrator -  Circuit Ideas for Designers App Note___ Advanced Linear Devices, Inc

Switched-Capacitor Integrator -  We can strap this circuit onto the front end of an opamp to create the basic building block of many filter circuits the integrator.  However, the major obstacle to happy filtering is the mine field of stray capacitance.  These uncontrolled strays can add significant capacitance to the switched capacitor, destroying the accuracy of your desired filter  __ Designed by Rick  last name not given

Ultra Long Time constant Integrator -  Circuit Ideas for Designers App Note___ Advanced Linear Devices, Inc

Use an Integrator Instead Of Coupling Capacitors -  02/16/12  EDN-Design Ideas Level-shift a signal with an unknown dc offset to a known offset without ac coupling.  An ultrasonic sensor circuit requiring self-adjustment to the level of an ac-input signal also must accommodate the signalís unknown and variable dc-bias voltage.  The circuit cannot use an ac coupling capacitor, and the resulting output must be level-shifted to a known dc offset.  The design uses a dc-offset compensator (Figure 1).  __ Circuit Design by Vladimir Rentyuk, Modul-98 Ltd, Zaporozhye, Ukraine
