Title: Problems with Rand Bit Stream AHDL Block
Post by repah on Oct 27^th, 2018, 8:07pm

Hello,

I want to measure the Eye Diagram of a Broadband Bipolar amplifier I designed.

When I use Rand Bit Stream - i get a lot of errors and the transistor breaking down at BE junction.

I do not get this error with MOS amplifiers.

What can I do - how can I measure the eye diagram of bipolar transistor properly with rand bit stream ?

Thanks.

You've given us very little to go on. Perhaps the transition time of the generator is too fast.
