5.6v zenners forward biased 🙂
Hi All,
Using the 5.6v zenners greatly improved temperature stability, there is only slight amplitude variation of a couple of percent between 0 deg C and 40 deg C.
BUT this high level of clamping resulted in very distorted output, with extra noise due to the reverse biased junctions.
So to fix this I placed the 5.6v Zenners in the circuit as forward biased, this reduced the clamping voltage and noise while retaining the temperature stability.
