- Control accurate incremental voltage steps with a rotary encoder
- In this respect, CMOS or JFET op-amps are best since they have extremely low input bias currents – usually in the picoamp range.
- Putting Tunable Light Sources to the Test
- The detection of low current requires very sensitive equipment with the ability to measure current down to the pico-ampere level. To make for an easier signal measurement, optical power is typically increased.
- Chatting with a Neuron
- The headstage and amplifier are the central components: the turnstile or communication hub between the researcher and the neuron (Figure 1).
- Sub-picoamp input op-amp offers high gain bandwidth
- Sub-picoamp input op-amp offers high gain bandwidth. Linear Tech is aiming at high-impedance sensor transimpedance amplifiers with an op-amp that requires only 3fA of bias current (typical at 25°C) while offering 500MHz gain bandwidth product.
Picoampere is described in multiple online sources, as addition to our editors' articles, see section below for printable documents, Picoampere books and related discussion.
