  • Why does power dissipation of a Darlington transistor tend higher than single bipolar transistor in switching apps?

    Issue 272: EQ Answers 30 Nov '16, 3pm

    —In switching applications, a single transistor can saturate, resulting in a low VCE of 0.3 to 0.4 V. However, in a Darlington pair, the output transistor is prevented from saturating by the negative feedback provided by the driver transistor. If the collector voltage drops below the ...

    Question 1: What is the probably of a flip-flop with a uniformly-distributed asynchronous input going metastable? Answer 1: The probably that a flip-flop with a uniformly-distributed asynchronous input will go metastable is a function of how wide its “window of opportunity” (the sum o...

  • The future of self-reconfiguring #robots

    Self-Reconfiguring Robotic Systems & M-Blocks 16 Nov '16, 5pm

    The creation of autonomous machines capable of shape-shifting has been a long-running dream of scientists and engineers. Our enthusiasm for these self-reconfiguring robots is fueled by fantastic science fiction blockbusters, but it stems from the potential that self-reconfiguring robo...

    Question 1: What is the second grid in a tetrode vacuum tube for? How about the third grid in a pentode? Answer 1: In a triode, there is a certain amount of capacitance between the control grid and the plate, which contributes to negative feedback and stability problems if there’s sig...

    Note that continuous conduction mode includes the case in which synchronous (active) rectification is being used and the current through the coil is allowed to reverse direction when the output is lightly loaded. The output voltage in relation to the input voltage will still be define...
