The TIA must also handle large voltage swings at its output with negligible nonlinear-ity. Moreover, the TIA must provide enough gain to overcome the noise of the subsequent stages.

Negative (into source) currents result in output voltage that is positive with respect to Vref. Drag a TIA component onto your design and double-click it to open the Configure dialog. This sets the capacitive
