How does the resistor connecting the non-inverting terminal to ground affect the transfer curve?

  • \$\begingroup\$ When is the output=0V? What should Rc be connected to if you wanted 0V out at Vcc/2? What is the input offset if Iin*R from input bias current is large? What should Rc be? \$\endgroup\$ – Tony Stewart Sunnyskyguy EE75 Mar 26 at 17:45

    \$\begingroup\$ It doesn't affect the transfer curve. It affects offset errors due to the input bias currents. \$\endgroup\$ – The Photon Mar 26 at 17:46
  • \$\begingroup\$ Depending upon the topology of the input diff-pairs (especially cascaded to reduce Miller Effect), charge blowback onto the RC can upset the region near zero-crossing. \$\endgroup\$ – analogsystemsrf Mar 27 at 4:35
