This includes the transistor which is important for the analogous tube circuit as well. The work is in NI Multisim which has been mainly for the SPICE simulation environment. Keywords SPICE, NI, Multisim. 1. INTRODUCTION The standards are set for this where the common emitter also gives the amplifier an inverted output that can be set for a higher gain. A proper stability is important for the high gain circuits so that there is no loss in energy. hence, the other forms of the lower input dynamic range is imposed with the higher distortion range. The common way is to alleviate the isues with the emitter degeneration that mainly refers to the addition of the smaller resistor or the impedance plan. 2. PRACTICAL MEASUREMENT 2.1 Experimental Circuit 2.2 Equipment and Component 2.3 Procedure This includes that the work is based on the PSPICE simulation process with proper calculation of the parameters set for the small signals that is equivalent to the internal capacitance of the resistor. It also includes the value of the change in the high cut-off frequency with the bandwidth that could be able to anayse the midband gain as well as the load resistance form. 2.4 Results The results include the integration of the circuit design with the different forms of the mockups as well as the SPICE perfroamnce for the Monte Carlo simulation. This includes the accurate forms of the component variations where the performance could easily be set depending upon the translations as well as the descriptions. 3. Theoretical Analysis 3.1 DC Conditions of the Single Amplifier For this, there is a need to make a choice on the transistor used. Along with this, there are certain other factors which includes the increase in the output impedance of the amplifier as well as handling the load resistor value as well. The calculatin of the value for the load resistor will help in analyzing the output signals as well as the other components that could be set under a preferred value. The setup is mainly with the bias stabilization, where the emitter voltage is about 10% to 15%. 3.2 Midband Gain of Single Amplifier For this, there is a need to analyse the frequency of the inputs as well as the inputs of the AC signals so that the transistor receives the key singals for the amplification. For the lower frequnecies, the tnaskistor amplifies the signal for the very little time. hence, the frequency increase where the bandwidth also reach the higher region of the frequency range. 3.3 High Cut off frequency The cut off frequency is mainly for handling the filters and the communication channels which could work on the low pass, high pass or the band stop characteristic. With this, there is also other band stop corner frequency that could be used for handling the transition. 3.4 DC Conditions There is a need to find the different variables which are set for the given circuit under a particular condition. The relevant equations are V=IR. The solution includes the capacitors as well as the other forms of the open circuits that could easily be used for handling the changes. 3.5 Midband Gain 4. PSPICE Simulation The work is based on handling the circult simulation programs where the derviatives are based on the connections as well as proper descriptions of the equations. It includes the differential forms of the algebraic equations which use the implicit integration methods as well as the Newton’s method. The basis are set to determine the cost as well as the development with the Linear technology intruments. SPICE includes the AC analysis with the DC analysis, transfer curve and the noise analysis that is important for the common emitter amplifier. NI Multisim is mainly for the designing of the programs as well as handling the microcontroller simulation. This will help in improting and exporting the differnet features which are based on the SPICE simulation. The standards are based on the interaction image technology where there is a proper maintaince of the Ultimate technology layout with the microcontroller simulation as well. 5. Result Analysis The common emitter amplifier tends to be lower mainly due to the higher capacitance that comes mainly from the Miller effect. The problems could easily be mitigated through the reduction in the voltage gain magnitude through the use of the emitter degeneration. The reduction of the output impedance of the original source which is then connected to the base. The use of the cascade confirmation also inserts the lower input that has been set with the use of the different forms of the amplifier topology. The standards are based on the performance as well as the source amplifer in a particular manner. The common emitter amplifier is set with the transistor that is common for the input and the output circuit. With this, there is also a common junction that could be used to compare the common base as well as the higher input impedance with lower output. 6. REFERENCES [1] Bowman, M., Debray, S.
