Webb25 juli 2024 · Simple Delay Timer Circuits Explained. In this post we discuss the making of simple delay timers using very ordinary components like transistors, capacitors and diodes. All these circuits will produce delay ON or delay OFF time intervals at the output for a predetermined period, from a few seconds to many minutes. Webb8 dec. 2024 · In a typical HBT, N e /P b ≈ 1/10. That is, the base is heavily doped compared to the emitter, minimizing base width modulation. Therefore β max =5 x 0.1 x 3000 ≈ 1500, which is a huge number. Therefore I p = I n / β max = I n / (1500), which is negligibly small compared to I n and can be ignored.
