An integrator is built with an opamp and a feedback capacitor acossing the output node and negative input node of the opamp. The input current charges the negative input node, and the negative input node will manitain virtual ground, and the output voltage has a ramp signal.
Where is the input current going? The input current can not across the feedback capacitor, and the input gate of the transistor is a high impedance. Thanks.
