Title: Current-input current-output integrator Post by rajeee1000 on Feb 22nd, 2012, 9:58pm Hi! Does somebody have an idea or information of the existing techniques to build a current-input current-output integrating function (i_out(t)=integ(i_in(t)dt), limits: -inf, t)? Please help; thanks. Best regards, Rajesh |

Use an op amp in a V to I converter configuration (see any op amp book) that what you are looking for? |
Title: Re: Current-input current-output integrator Post by raja.cedt on Feb 24th, 2012, 2:26am hello, as rf idea and loose electron said, just dump some current into cap and convert that voltage into voltage by V2I converter. In fact all integrators are based current input, but we are interested to integrate voltage so we used to keep resister to converter voltage into current. Thanks, Raj. |
