A current amplifier is disclosed, the current gain of which varies directly with changes in input current. A first transistor, arranged as a slave mirroring transistor provides output signal current responsive to a multi-mode transistor master mirroring circuit. The master mirroring circuit includes ...
Since each part, regardless of its architecture, has some trimmed input resistance, any external resistance added in series will produce mismatches leading to both gain- and CMR errors, typically calculated as follows (Rin is the specified amplifier input resistance):...

Transducer secondary current is sensed on a low-ohmic precision burden resistor by a programmable gain amplifier, driving theHybridADC analog-to-digital converter technology. Total DC-CT current sensing accuracy is thus a sum of errors from the DC-CT core, the amplifiers, a voltage reference, an...
A digitally programmable gain amplifier for ultra-low-power applications The gain of the digitally programmable gain amplifier is regulated by using current digital signal level without switch requirements; hence low circuit ...

The ADC_DelSig has control over the Vref, Input Range and the Buffer gain. For example with the circuit above, using Vref = 1.024V, Input range = Vssa to 1.024V and Buffer gain = 1 you get 16bits of ADC resolution from 0 to 100nA. (Remember you're going...
The high-impedance node is a frequency-dependent impedance, Z(s), analogous to the open-loop gain of a voltage feedback amplifier; it has a high dc value and rolls off at 20 dB/decade. The closed-loop transfer function is found by summing the currents at the VIN node, while the ...
