What collector current is required for a bipolar transistor to achieve a transconductance of 5.5 mS ? Use VT=0.026V and express your answer in µA up to 2 decimal places. b. A transistor operating with nominal gm of 80 mS has a ββ that ranges from 50 to 150. Also, the bias circuit, being less than ideal, allows a 20% variation in ICIC. What is the smallest value found of the resistance looking into the base, in kΩkΩ? Use VT=0.026VT=0.026V and express your answer up to 3 decimal places. c. Given that a BJT is biased to have a small signal input resistance rπ = 25 kΩkΩ with β = 100, what is the BJT's transconductance gmgm? Use VT=0.026VT=0.026V and express
Power Amplifier
The power amplifier is an electronic amplifier designed to maximize the signal strength of a given input. The input signal strength is enhanced to a high enough level to drive output devices such as speakers, headphones, RF (Radio frequency) transmitters, etc. Unlike voltage / current amplifiers, the power amplifier is designed to drive core loads directly and is used as a storage block in the amplifier series.
Maximum Efficiency Criterion
In every field of engineering, there is a tremendous use of the machine and all those machines are equipped for their popular work efficiency so it very much important for operation engineers to monitor the efficiency of the machine, planning engineers to check out the efficiency of the machine before installing the machine and design engineers to design machine for higher efficiency than and then the utility will procure their products that will ultimately lead to profit and loss of the company. It indicates the importance of efficiency right from the initial stage as manufacturing units, intermediate stage as planning coordinators, and end-users stage as a utility.
