In this circuit, the voltage divider holds the base voltage fixed independent of base current provided the divider current is large compared to the base current.
42.
As with any oscillator, the amplification of the active component should be marginally larger than the attenuation of the capacitive voltage divider, to obtain stable operation.
43.
This problem is avoided in the Clapp circuit by using fixed capacitors in the voltage divider and a variable capacitor ( C0 ) in series with the inductor.
44.
Probes intended for up to 100 kV typically employ a resistor voltage divider, with an input resistance of hundreds or thousands of megohms to minimize circuit loading.
45.
With just the voltage divider, resistor tolerance, temperature and device selection will all impact your measurement and at the low end, it will be useless.
46.
Real power supplies that source large currents do not use voltage dividers to set the output voltage . talk ) 17 : 37, 20 July 2014 ( UTC)

In this arrangement, attenuation and summation are separated : a voltage divider acts as an attenuator and the loop acts as a simple op-amp inverting Schmitt trigger, etc.
48.
In this case, the base voltage divider is usually connected to the transistor's collector rather than V CC, providing negative feedback that stabilizes I E and I C.
49.
You could use passive voltage dividers with a single common voltage rail, but this is terribly wasteful since all the power dissipated by those resistors is more or less wasted energy.
50.
The upward movement of the high-frequency pole occurs because the Miller-amplified compensation capacitor " C C " alters the frequency dependence of the output voltage divider.
