Problem Statement: Design a small-signal voltage amplifier using BJT's that meets the following specifications: 1) Voltage gain of 50 or more 2) Minimum input resistance of 15 k? 3) Output resistance less than 100 ? 4) Maximum unclipped output of 2V peak-to-peak 5) Power supply voltage of 9 V 6) Lower current drain from supply voltage?
Hint: You may use a multi-stage small-signal amplifier to achieve desirable input resistance, voltage gain, output resisntace, etc. A common-emitter amplifier with an emitter resistance RE, but without an emitter by-pass capacitor CE is good for high input resistance, common-emitter amplifier using an emitter bypass capacitor is good for high voltage gain, and the use of an emitter follower results in a low output resistance.
A quantity of 432 mg of an amino acid with a neutral side chain consumes 7.39 mEq of acid as well as base in the titration range of 0.8 to 12.0. Explain what is the name of the amino acid
How many mL of a 22.5% (v/v) ethanol solution would you need to measure out in order to have 12.5 mL of ethanol? The Molar Mass of ethanol is 46.07g/mol.
What is the minimum external voltage must one supply in orger to perform the electrolsis of molten CaCl_2(l)? Suggest a means for supplying this energy.
Problem- i). An iron ore is analyzed for iron content by dissolving in acid, converting the iron to Fe2+, and then titrating with standard 0.0150 M K2Cr2O7 solution. If 35.6 mL is required to titrate the iron in a 1.68 g sample, how much Fe2+ is i..
