要約(英語)：This paper proposes a new transimpedance amplifier circuit based on an inverter TIA (INV-TIA) circuit and a regulated cascode TIA (RGC-TIA) circuit. The proposed TIA circuit has higher gain and wider bandwidth operation than conventional TIA circuits. Pre-layout simulation shows that the proposed TIA circuit achieves a transimpedance gain of 65.5 dBOmega and a bandwidth of 21.9 GHz. For a supply voltage of 1.2 V, the power consumption is 7.0 mW, the equivalent input current noise is 14.0 pA/sqrtHz, and the eye aperture is 81%.
