Optional trimming of output offset voltage
WebOptional trimming of input offset voltage took place at pins 1−8, where an external 100 KΩ pot with the wiper to +V S was adjusted for lowest offset. When done in this manner, this also gave lowest drift. Some circuit subtleties are belied by … WebThe offset is trimmed for both high and low common-mode conditions so that the offset voltage is under 500 µV over the full common-mode input voltage range. The bandwidth …

WebThe LT1920 is laser trimmed for very low input offset voltage (125 µV max), drift (1µV/°C), high CMRR (75dB, G = 1) and PSRR (80dB, G = 1). Low input bias currents of 2nA max are achieved with the use of superbeta processing. The output can handle capacitive loads up to 1000pF in any gain configu- WebBased on this, the main idea behind the proposed offset cancellation technique is to use body-voltage trimming in order to change the threshold voltage of the one of the input PMOS transistors (M 1/M 2) in such a way that the differential current (i diff), generated due to the mismatch effect, will be cancelled.
Weboffset to balance the offset of the OA. Tune the potentiometer until the offset on the output disappears. Method 2: Internal Balance Trim Use the “offset null” or “balance” pins provided by most OAs (e.g., OAs shown in Figure A.1). 1.
