In this paper, a cross-coupled gain-boosting current-mode integrator is proposed, which is better than typical current mirror integrator when compared in terms of increasing gain and frequency response. The results of small signal equivalent circuit analysis and HSPICE simulation of the proposed integrator show that gain and frequency response is improved at supply voltages of 1V band. An example application using the proposed integrator low- voltage current-mode filter is also presented. The simulated cutoff frequency of the designed filter is 200MHz at a supply voltage of 1.8V.
