Method and apparatus for random sequence generator

An apparatus, comprising:

• a) a white noise source that produces white noise for processing;
• b) a gain stage differentially coupled to said white noise source, said gain stage having a cascade of open loop amplifiers to produce amplified white noise;
• c) a noise shaping stage differentially coupled to said gain stage to produce shaped white noise having less 1/f noise and offset than said amplified white noise;
• and
• d) a decision circuit differentially coupled to said noise shaping stage that decides whether said shaped white noise is a 1 or 0.

A method, comprising:

• a) differentially coupling white noise into a gain stage;
• b) differentially amplifying said white noise with an amplifier to produce a first white noise signal;
• c) reducing 1/f noise and offset voltage from said first white noise signal to produce a second white noise signal;
• and
• d) deciding whether said second white noise signal is a 1 or 0 to produce a random sequence signal.
