*4.3. TIA Design*

The transimpedance amplifier (TIA) is used to convert the IF current to an IF voltage at the output. The TIA circuit is formed by transistors MTIA and feedback resistors RFB, where an additional harmonic recombination circuit is not required. The length of MTIA should be large enough to enhance the output impedance. The conversion gain of the proposed stacked receiver can be calculated using Equation (7).
