Suppose the negative terminals of Vin and Vout in Fig. 3.38(b) are shorted together. Plot the input-output characteristic assuming an ideal diode model and explaining why the circuit does not operate as a full-wave rectifier.
Design a buck converter that has an output of 12 V from an input of 18 V. The output power is 10 W. The output voltage ripple must be no more than 100 mV p-p. Specify the duty ratio, switching frequency, and inductor and capacitor values.
Design limiter circuits using only diodes and 10-k ohm resistors to provide an output signal limited to the range: (a) -0.7V and above (b) -2.1V and above (c) ±1.4V Assume that each diode has a 0.7-V drop when conducting.
A 3-phase, 440VAC, 6-pole, 60Hz, wye connected induction motor takes 30KVA at .8 power factor lagging, and runs at a slip of 3.5% at full load. The stator copper losses are 500W, and the rotational losses are 350W.
An infinitely long coaxial capacitor with inner conductor radius aand outer radius b has voltage V0 on the inner conductorand V = 0 on the outer conductor. Find the electric field inthe region between the two conductors.
An FCT three-state buffer drives ten FCT inputs and a 4.7kΩ pull-up resistor to 5V. When the output changes from LOW to Hi-Z, estimate how long it takes for the FCT inputs to see the output as HIGH.
You are designing a general purpose integrated circuit oscillator that will operate at various frequencies, based on the external reactancesthe user supplies. You expect that the IC will be used as afixed frequency oscillator in portable equipment..
Construct a 16-bit parallel adder with four MSI circuits, each containing a4-bit parallel adder. Use a block diagram with nine inputs and fiveoutputs for each 4-bit adder. Show how the carries are connected between the MSI circuits.
Develop the VHDL text file for a binary down-counter to divide a frequency by 32. Use Q as the outputs and CLK as the falling edge clock input.
a 60-kHz sinusoidal signal is applied to an amplifier with a gain of k=2. the circuit is built with an lm741 opamp with power supplies +-13V. find the largest amplitude the signal may have before it is limited by slew rate constraints.
A container having a volume of 0.2 m3 contains nitrogen at a pressure of 100 kPa and a temperature of 15°C. If 0.2 kg of nitrogen is pumped into this container, calculate the final pressure after the gas has returned to its initial temperature.
A harmonic wave traveling along a string is generated by an oscillator that completes 180 vibrations per minute. If it isobserved that a given crest, or maximum, travels 300 cm in 10s,what is the wavelength
Mike and Susan hope to retire a few years early, they decided to pay closer attention to the predicted amount of retirement benefits and do some analyses on the numbers. They found that their projected benefits are substantially the same.
