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 10):
The trans-impedance amplifier as recited in  claim 9 , wherein said feedforward amplifier is a fourth complementary pair of a fourth NiFET and a fourth PiFET, each of said fourth NiFET and said fourth PiFET comprises:\n a diffusion terminal of a corresponding conductivity type of said each of said fourth PiFET and said fourth NiFET, defining a source channel between a source terminal and said diffusion terminal, and a drain channel between a drain terminal and said diffusion terminal, said diffusion terminal causes changes in said diffused charge density throughout said source and drain channels, and a gate terminal capacitively coupled to said source channel and said drain channel; wherein said gate terminal of said fourth PiFET and said gate terminal of said fourth NiFET are connected together to form a common gate terminal, said source terminal of said fourth NiFET is connected to negative power supply and said source terminal of said fourth PiFET is connected to positive power supply, and drain terminals of said fourth NiFET and fourth third PiFET are connected together to form said output of said feedforward amplifier; wherein said common gate of said fourth complementary pair receives said output of said last one of said plurality of complimentary pairs.
