| description | The article deals with a low pass op-amp model with high gain at DC and a single-pole frequency response and presents a technique for simple analysis of negative inductance compensator (NIC) circuits. Analytical expressions are derived fo r NIC frequency response analysis in case of operational amplifier finite bandwidth. Besides, the ideal NIC circuit comparison results are provided. Calculations show that op-amp finite bandwidth has impact on NIC impedance at fre quencies 10 times lower than gain-bandwidth product. The obtained analytical results are in good agreement with experimental setup measurements of NIC implementation to electrically small antenna impedance matching. |
