This paper describes a power amplifier, employing parallel-connected laterally diffused metal–oxide semiconductor (LDMOS) devices with optimized channel widths and bias offsets to approximate ideal square-law behavior of the overall transconductance in class-AB operation. The proposed method results in a significant linearity improvement over a large dynamic range in comparison to a conventiona...

This paper provides an alternative and highly accurate method in predicting Small Signal Performance of Microwave Amplifier. An Electromagnetic (EM) simulator that based on Finite Element Method (FEM) was used in combination with the conventional SPICE-based microwave circuit simulator in order to demonstrate the superiority in performance outcome such as Rollet Stability Factor (K), Return Los...

The tracking performance of non-linear amplifier based conventional second order phase locked loop (PLL) and charge pump phase locked loop have been examined numerically by solving the system equations in the presence of lognormal type of fading signal. Some analytical results for non-linear amplifier based conventional phase locked loop and charge pump phase locked loop are also incorporated t...

This paper presents a high CMRR and wideband current feedback Instrumentation Amplifier (IA). The proposed IA architecture consists of Fully Balanced Differential Difference Amplifier (FBDDA) and Differential Difference Amplifier (DDA) based on 2 generation current conveyor (CCII) with a buffer. From the simulation results evaluated by HSPICE, the proposed IA exhibits average CMRR was 109.3 dB ...
