Chapter 7, Problem D7.2P

6b. The transistor consists of three terminals. The main reason for designing configurations is that it requires four terminals in order to provide the input and the output connections of the circuit for effective amplification. Now in your own words describe how Bipolar Transistors Transistor ( BJT ) various configurations are designed with relating  diagrams.  In your own estimation evalute which one is most widely used when looking at appreciable output for an amplifier?

Design a voltage-divider bias network using a supply of 24 V, a transistor with a beta of 110, and an operating point of ICQ = 4 mA and VCEQ = 8 V. Choose VE = 1/8 VCC. * Here designing means find the values of the resistors for the circuit.

6) the "simplest" model of transistor behavior in this problem, i.e., B = o and IB = 0, with forward bias voltage of AVBE = 0.6V. Consider the following circuit with a transistor and two resistors. You may use 5V a) Determine the output when Vin = 0.5V. 9kN Vout Vin 3002 3kN b) Determine the output when Vin = 1.2 V. c) Determine the output when Vin = 3.6 V.

D7.35 The bias arrangement of Fig. 7.53 is to be used for a common-base amplifier. Design the circuit to establish a de emitter current of 1 mA and provide the highest possible voltage gain while allowing for a signal swing at the collector of ±2 V. Use +10-V and -5-V power supplies. R₂4 +Vcc RE -VEE Figure 7.53 Biasing the BJT using two power supplies. Resistor R is needed only if the signal is to be capacitively coupled to the base. Otherwise, the base can be connected directly to ground, or to a grounded signal source, resulting in almost total 8-independence of the bias current.

The steady state operation of a transistor depends a great deal on its base current, collector voltage, and collector current values and therefore, if the transistor is to operate correctly as a linear amplifier, it must be properly biased. In your level of understanding, explain how important biasing transistor in a given working electronic Circuit is. Explain also the consequence when such transistor does not biases properly

Design an NPN based common emitter amplifier that meets the following specifications: Voltage Gain: 35dB min, 45DB max Input Resistance: Rin 2 5kn Output Resistance: Rout < 5kn The amplifier should use bypass capacitors that isolate the de portion of the circuit. Use any number of resistors you feel is sufficient to meet the circuit specifications. All resistors and capacitors do not have to be standard values.
