A novel wide range electrometer with quasilinear output
نویسنده
چکیده
An electrometer using complementary metal–oxide–semiconductor bilateral switches for automatic range control is described. Based on a dual-switching configuration, the electrometer is capable of current measurement over eight orders of magnitude. Together with a voltage shifter, this circuit provides a quasilinear analog output for the measurement of input dc current between 10 and 10 A. The application of integrated circuits makes the whole system compact and extremely low cost. © 1997 American Institute of Physics. @S0034-6748~97!03510-7#

متن کاملAn integrated-circuit based wide range electrometer implemented with automatically ranged linear display
In the measurement of dc current for the range of 10-6-10-‘2 A, a stable electrometer is required. The electrometer circuit is usually implemented by simply probing the voltage drop on a load resistor using a sensitive voltage amplifier.’ In this scheme, different values of the load resistor are needed to cover multi decade range without saturating the voltage amplifier. This results in differe...
