Parameter definitions
Common mode rejection ratio (CMR)
The common mode rejection ratio (CMR) measures the ability of the current sensing
amplifier to reject any DC voltage applied on both inputs V
back to the input so that its effect can be compared with the applied differential signal. The
CMR is defined by the formula:
Supply voltage rejection ratio (SVR)
The supply voltage rejection ratio (SVR) measures the ability of the current-sensing
amplifier to reject any variation of the supply voltage V
input so that its effect can be compared with the applied differential signal. The SVR is
defined by the formula:
Gain (Av) and input offset voltage (V
The input offset voltage is defined as the intersection between the linear regression of the
