TIEF-SUBMIKROMETER-MOS-VORVERSTÄRKER MIT DICKOXID-EINGABESTUFE-TRANSISTOR

The present invention relates to a condenser microphone assembly comprising a condenser microphone transducer comprising adjacently positioned diaphragm and back-plate members having an air gap there between. Moreover, the assembly comprises a deep sub-micron MOS integrated circuit die comprising a preamplifier comprising a first signal input terminal for receipt of electrical signals generated by the condenser microphone transducer. The first signal input terminal is operatively coupled to an input stage of the preamplifier, said input stage comprising a thick-oxide transistor. The present invention further relates to a deep sub-micron MOS integrated circuit die comprising a thick-oxide transistor-based preamplifier.
