Modeling and Performance Evaluationof a TIACMOS Amplifier with Shunt Inductive Feedback at 0.18 μm CMOS Technology

In contemporary analog circuit design, designing a transimpedance amplifier (TIA) using Complementary Metal-Oxide-Semiconductor (CMOS) technology is essential, especially for high-speed, low-noise applications. PMOS and NMOS in shunt inductive negative feedback transistors are used in this proposed design to increase power efficiency, gain, and bandwidth. Complementary transistor pairs drive the output of the planned CMOS TIA. The primary benefit of this configuration is the ability to maintain high bandwidth while offering low output impedance. The design arrangement effectively supports positive and negative fluctuations, reducing distortion and improving linearity. This is crucial for high-speed signal processing applications, such as optical receivers. By operating the suggested system, a gain of 64 dB is achieved. Noise and speed performance are balanced by adjusting the transimpedance gain. CMOS TIA systems achieve a gain-bandwidth quotient (GBP) of 786 MHz, a crucial factor. The gain-bandwidth quotient shows the amplifier's capacity to sustain high gain and broad frequency response.
