Application, design and symbolic analysis of a current follower

A new circuit called a current follower, is described. It may be used with voltage followers to replace operational amplifiers. The advantages are at high frequencies, where the operational amplifier is unsuitable because of its limited frequency response and slew rate. Basic applications for these purposes are given. An, analysis of the internal nonlinear equations of the designed linear circuit is given. The analysis of the linear model of this circuit shows a typical example of the application of the symbolic networkanalysis program Netform. Extremely short computation times are observed in a nontrivial situation, due to the newly implemented double sparse Laplace expansion (d.s.l.e.) method.
