Fig.Q1 is a modified Howland voltage controlled current source (VCCS). Analyse the circuit to obtain an expression for the transconductance gain and the relative resistor values needed for the circuit to approach the ideal VCCS performance. 12 RI OA Vx lin VL 13 O- Vin R3 R4 It RL Fig.Q1 R2 Fig.Q1 is a modified Howland voltage controlled current source (VCCS).
