Abstract:
The present invention relates to a novel and inventive compound device structure for a low noise current amplifier or trans-impedance amplifier. The trans-impedance amplifier includes an amplifier portion, which converts current input into voltage using a complimentary pair of novel n-type and p-type current field-effect transistors (NiFET and PiFET) and a bias generation portion using another complimentary pair of NiFET and PiFET. Trans-impedance of NiFET and PiFET and its gain may be configured and programmed by a ratio of width (W) over length (L) of source channel over the width (W) over length (L) of drain channel (W/L of source channel/W/L of drain channel).

Claim (Index 7):
The trans-impedance amplifier as recited in  claim 5 , wherein said output amplifier comprises a plurality of complementary pairs of a third NiFET and a third PiFET, wherein\n each of said third NiFET and said third PiFET comprises: a source terminal, a drain terminal, a gate terminal, and a diffusion terminal of a corresponding conductivity type of said each of said third PiFET and said third NiFET, defining a source channel between said source terminal and said diffusion terminal, and a drain channel between said drain terminal and said diffusion terminal, said diffusion terminal causes changes in said diffused charge density throughout said source and drain channels, and said gate terminal is capacitively coupled to said source channel and said drain channel; wherein said gate terminal of said third PiFET and said gate terminal of said third NiFET are connected together to form a common gate terminal, said source terminal of said third NiFET is connected to negative power supply and said source terminal of said third PiFET is connected to positive power supply, and drain terminals of said third NiFET and said third PiFET are connected together to form an output of each of said plurality of complementary pairs; wherein said common gate of a subsequent one of said plurality of complementary pairs receives said output of a prior one of said plurality of complementary pairs; and wherein said common gate of said first one of said plurality of complementary pairs receives said output of said first complimentary pair.
