Am·père

(ahm'pēr),
André-Marie, French physicist, 1775-1836. See: ampere, statampere, Ampère postulate.

am·pere (A),

(am'pēr),
1. The practical unit of electrical current; the absolute, practical ampere originally was defined as having the value of one tenth of the electromagnetic unit.
2. Legal definition: the current that, flowing for 1 second, will deposit 1.118 mg of silver from silver nitrate solution.
3. Scientific (SI) definition: the current that, if maintained in two straight parallel conductors of infinite length and of negligible circular cross-sections and placed 1 m apart in a vacuum, produces between them a force of 2 × 10-7 N/m of length.

The values for the input resistance found in the control rats are between 24 and 316.5 K[OMEGA], and their corresponding threshold currents range from 94 to 1,232 nanoamperes. Similar input resistance and threshold current values were observed in both groups.
Do you need to measure nanoamperes of DC current with picoampere resolution?
Second, AEC sensors are characterized by an output signal that, ranging from a few nanoamperes to several microamperes, imposes conflicting requirements on the current voltage digitalization circuit--a high gain design can sense low gas concentrations but may saturate, while a low gain circuit suffers from reduced resolution but possesses a wider dynamic range.
