Design a small-signal voltage amplifier that meets the following specifications:1) Voltage gain of 50 or more2) Minimum input resistance of 15k -ohm3) Output resistance less than 100 -ohm4) Maximum unclipped output of 2V peak-to-peak 5) Power supply voltage of 9 V6) Lower current drain from supply voltage
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 by- pass capacitor is good for high voltage gain, and the use of an emitter follower results in a low output resistance.
In a power supply, a 150 microfarad capacitor was connected in parallel with a 200 kOhm resistor. The capacitor was maintained at a charge level of 350 volts DC. After power was removed for ten seconds, someone god a shock from touching the termin..
a bar of n-type germanium and we place an E field going to the right across it and create a pulse of excess minority carriers (holes) in the center of the bar at time t=0. In other words we are performing the Haynes Shockley Experiment on the bar
A filamentary current along thex axis has a current in the b a x direction. A square loop of current in the xy plane centeredat (0,10,0) has a current in the counter-clockwise direction. What is the direction of the netforce on the loop
Design a circuit that, given a 2-bit value, will light a LED corresponding to that value. One of four LEDs should be lit for each of the four possible input values (binary 0 through 3).
a defibrillator supplies a maximum energy dosage of 20 jouls, and the maximum voltage of 8 volt. suppose it is desired to charge the capacitor from an ideal DC current source, and they want to do it in less than 80 seconds.
Electrical wiring: Potentials of neutral and earth wires, Why is the neutral wire in housing circuits also at zero potential
A continuous time system, described by y(t) = 5 Cos (2*pi*20*t + pi/2), is sampled at a rate 320 Hz. (a) Write the mathematical expression that describes the discrete time (sampled) signal. (b) Calculate the value of the discrete signal for n = ..
A pn junction diode has Vd= 690 mv, C=6pF, Id= 500 microamps, Vt=.0259 V. It also has C=4pF when Id= 100 microamps. Derive the complete high-frequency model when Vd=610mV.
A circuit that is made from a voltage source in series with the switch then in series with the parallel set of a resistor and a capacitor. The switch is originally open, it is then closed.
Model and simulate a 4-to-1 multiplexer using (a) Dataflow Modeling, (b) Behavioral Modeling, and (c) Structural Modeling. Use Modelsim and a VHDL test bench to simulate all the three models for a 4-to-1 multiplexer.
Prompt the user to enter a letter indicating Celsius or Fahrenheit C or c indicates that temperature entered is in Celsius. F or f indicates that temperature entered is in Fahrenheit.
A perfect conductor with bias voltage Vo is insulated with a wedge shaped dielectric material of angle, =450, whose relative permittivity is εr. Use electrostatic boundary conditions to determine the electric displacement, D
