We wish to estimate the d-c power dissipated in a GaAs Gunn diode. Assume that the diode is 5 jxm long and operates in the stable domain mode.
(a) What is the minimum electron concentration n0l What is the time between current pulses?
(b) Using data from Fig. 10-9a, calculate the power dissipated in the sample per unit volume when it is biased just below threshold if rc0 is chosen from the calculation of part (a). In general, does operation at a higher frequency result in greater power dissipation?
It starts from rest at the origin. Show that it moves in a cycloidal path and drift velocity or the velocity of the center of the rolling circle along the z axis. If the electric field is 10^4 volts/cm, and the magnetic field 10^4 gausses. find th..
Write a computer program to solve the dispersion relation V(1-b)^0.5 =mπ+arctan(b/(1-b))+arctan((b+a)/(1-b)). (a) We wish to fabricate a planar waveguide in GaAs (n = 3.6) for light of wavelength λ = 1.3 μm that will operate only in the fundamen..

A PWM is used in 8-bit mode to produce a signal with a 1 msec period and 60% duty cycle. Determine the value required for any pre-scaling, and the values for the period, and duty cycle registers. The E-clock is 24 MHz.
Write the assembly code to specify an array named src that holds values: 01, 23, 45, 67, 89, and an array of five variables named dst, then write the code to copy the values in array src to array dst.
Now, suppose that an initial voltage of 1V is present at the capacitor at zero time (t = 0). Will the behavior of the circuit when a step input is applied still yield an exponential rise or will the behavior be of some other type
