建立了一种准对数电流-电压转换器，可以测量从10pa到10ma的异常宽范围电流，带宽大于2khz。该变换器基于虚拟地方案，在反馈路径中采用半导体二极管作为非线性元件。它非常适合于研究扫描隧道显微镜中的局部相互作用。(C) 1997年美国物理研究所。
A quasilogarithmic current-voltage converter has been built which allows currents spanning an exceptionally broad range from 10 pA to 10 mA with a bandwidth greater than 2 kHz to be measured. The converter is based on the virtual ground scheme employing semiconductor diodes as nonlinear elements in the feedback path. it is ideally suited for studying local interactions in scanning tunneling microscopy.
