In addition, the bias current " I " " BIAS " is set by a single global transistor that is common to all the inputs.
32.
To the extent that the input bias currents do not match, there will be an effective input offset voltage present, which can lead to problems in circuit performance.
33.
Q3 is a common emitter stage that provides amplification of the signal and the DC bias current through D1 and D2 to generate a bias voltage for the output devices.
34.
The latter approximation assumes that the bias current I _ Q is large enough so that the factor of 1 in the parentheses of the Shockley diode equation can be ignored.
35.
The darlington output buffers on the LM13700 are different from those on the LM13600 in that their bias currents ( and hence their output DC levels ) are independent of IABC pin.
36.
The chalcogenide resistance being a necessarily larger resistance than the diode entails that the operating voltage must exceed 1 V by a wide margin to guarantee adequate forward bias current from the diode.
37.
As expected, the output corresponding to the larger of the two inputs carries the entire bias current ( 10nA in this case ), forcing the other output current nearly to zero.
38.
This inductance depends on the value of phase \ delta _ 0 at the minimum in the washboard potential, so the inductance value can be controlled by changing the bias current I.
39.
The detector allows the build up of detected infrared signal in a mercury cadmium telluride ( MCT ) photoconductor strip, on a sapphire substrate, by applying a bias current through the strip.
40.
This does not change the principles of the circuit's operation, but it does reduce the amplitude of the output at equilibrium because the bias current provides part of the heating of the lamp.
