This invention introduces a highly efficient current generator designed to produce precise square wave currents across a wide range, from nanoamps to microamps, with minimal noise and improved accuracy. By employing a single floating current source, it effectively cancels out noise and mismatches that typically arise from multiple sources, ensuring reliable measurements. The system mitigates errors caused by parasitic capacitances, maintaining linearity over a broad range of resistances and expanding its applicability to capacitive sensing applications through parameter adjustments.
