WebExplanation: Overdrive during BJT saturation is the ratio of its normal β and its forced β. Forced β is the ratio of I C (sat) and I B when BJT is in saturation. Since in saturation I C is constant and I B increases thus, I C /I B decreases and the forced β is less than the normal β. Hence the overdrive > 1. In hard/strong saturation, β>>1.

WebOne way to bias a BJT transistor is a method called base bias. Base bias the simplest way to bias a BJT transistor. Base bias ensures that the voltage fed to the base, V BB, is the correct voltage, which then supplies the correct current so that the BJT has enough base current to switch the transistor on. Below is a typical BJT receiving base bias: WebCrystal Oscillators. Whenever an oscillator is under continuous operation, its frequency stability gets affected. There occur changes in its frequency. The main factors that affect the frequency of an oscillator are. In RC and LC oscillators the values of resistance, capacitance and inductance vary with temperature and hence the frequency gets ...
