Standard Cell This project would involve some standard cells of cmos digital circuit. Some basic logic circuit can be made by using these standard cells. 1.1 Inverter Inverter is a very basic stand cell, which output is opposite of input voltage. Fig. 1.1 is the symbol of inverter. In this symbol, the vdd is voltage supply, gnd is ground, vin is input voltage, and vout is the output voltage. Figure 1.1 Symbol of Inverter Fig 1.2 is the cmos digital circuit of inverter, because the transmit speed of Pmos is faster than Nmos, so the width of Pmos should be 2 to 3 times bigger than width of Nmos. In Fig. 2, the width of Pmos is 320 nm, and the Nmos is 160 nm. In this library, there is a “subc” parameter which is essential in every Nmos, which can help the base of Nmos connect to the ground. Figure 1.2 CMOS circuit of Inverter Fig 1.3 is Noise of inverter, the noise is obviously in low frequency, the reason is the size of cmos gate is very small, therefore, the leak voltage ...

In electronics, the power amplifier class is an alphabetic symbol applied to different types of power amplifiers. This class provides an extensive description of the characteristics and performance of amplifiers. These categories are related to the time period during which the active amplifier device passes current, expressed as part of the period of the signal waveform applied to the input. In this paper, we will talk about different type power amplifier and mainly focus on Class E amplifier, including it's structure and theory.  1.1 Class B Amplifier Class B  amplifier improves the full power efficiency of the ordinary Class A configurations. This power amplifier is one of the most commonly amplifier, which often be used as error amplifier, Current-to-voltage converter, and Bromley amplifier. Figure 1.1 is the basic configuration of Class B Amplifier. While the gate voltage (Vsin) is positive, M1 will be turned on and VDD start charge the inductive load (R Load). While ...
