-Calculation-
1. Input Offset Voltage (Vio)
| VF1 |
Vio =
[V]
1 + Rf / Rs
2. Input Offset Current (Iio)
| VF2－VF1 |
Iio =
[A]
Ri ×(1 + Rf / Rs)
3. Input Bias Current (Ib)
| VF4－VF3 |
Ib =
[A]
2×Ri× (1 + Rf / Rs)
4.
Large Signal Voltage Gain (Av)
Av = 20×Log
ΔEK×(1+Rf /Rs)
[dB]
| VF 5-VF 6|
5. Common-mode Rejection Ratio (CMRR)
CMRR = 20×Log ΔVicm×(1+Rf /Rs) [dB]
| VF 8-VF 7|
6. Power Supply Rejection Ratio (PSRR)
PSRR = 20×Log ΔVcc×(1+Rf /Rs) [dB]
| VF 10-VF 9|
