“…In past history, following the stated purpose, many techniques and fabrication technologies were employed. An inductorless modified regulated cascode [1], shunt-shunt feedback [2][3][4] and active feedback transimpedance amplifier (TIA) [5] [6] were introduced. As for active inductor incorporation within various topologies, an active inductor peaking was realized [7], a current-reuse TIA [8], a TIA using active inductor in shunt and series techniques [9] and a common source TIA with active inductive peaking [10] .…”

A simulated 90 nm active inductor feedback transimpedance amplifier is reported. A 1V configuration of regulated cascode followed by a shunt-shunt feedback stage is considered with a local active inductor feedback configuration. A transimpedance gain of 62.9 dBΩ is achieved with a bandwidth of 2.7 GHz, power consumption of 1.22 mW and an input referred noise current spectral density of 21 pA/√Hz. The key advantage of using local active inductor feedback is to solve a major problem regarding integrated circuit design constraint in which it replaces an ordinary spiral inductor and therefore, real advantages of less volume on board a chip, low power consumption and input referred noise are obtained. Important transient analysis and Fourier transform analysis were performed to examine active inductor feedback system response. There was no apparent inductive peaking associated with transimpedance gain despite of the fact that the frequency response of active inductor impedance behavior was to a greater extent similar to that of an ordinary spiral inductor.
