These factors are therefore expected to provide lucrative growth opportunities during the forecast period.

Global CMOS Power Amplifier Market: Restraints

Technical Downsides of CMOS Power Amplifier Design

Although CMOS power amplifiers offer low cost and highly integrated wireless communication, these have several drawbacks that hinder its adoption. Major challenges associated with CMOS power amplifiers are nonlinearity, low breakdown voltage, lack of high voltage capacitors, and RF model inaccuracy. CMOS power amplifiers are inherently non-linear, and can introduce distortion. This is not an ideal choice for modern high PAR (peak-to-average) modulation techniques. CMOS amplifiers have higher development costs and longer manufacturing times than other technologies. Therefore, these factors are expected to restrain market growth during the forecast period. Implement linearization techniques such as pre-distortion, forward correction, or feedback to compensate for the nonlinear operation of the CMOS power amplifier. These methods can help improve linearity and reduce distortion. Use a digital signal processing algorithm to apply pre-distortion to the input signal before amplification. This can help counteract the non-linear characteristics of CMOS PA and achieve better linearity.

Issues Regarding Current Leakage

CMOS offers great benefits to the telecom industry, but current leakage remains the biggest problem. Leakage current can cause serious problems throughout the circuit including excessive power consumption, faults and/or short circuits. Such major drawbacks complicate its adoption, thereby, hampering market growth in the near future. Designers can implement a variety of techniques, such as reducing source voltage, using thicker gate oxides, and optimizing transistor geometry, to minimize leakage currents while maintaining maintain acceptable performance.
