Direct-Coupled GaAs Monolithic IC Amplifiers
Microwave and Millimeter-Wave Monolithic Circuits, 2005A two-stage GaAs FET monolithic amplifier has been developed that exhibits a noise figure of 2dB and a gain of 20dB at frequencies from 0.3 to 1.5 GHz. The FET gate width is optimized to 1mm to lower the noise figure for a 50 Omega signal source impedance. A direct-coupled scheme is used for chip size reduction.

CASCODE FINFET DIRECT COUPLED AMPLIFIER USING CADENCE FINFET TECHNOLOGY
2023Abstract A direct-coupled amplifier is a type of electronic amplifier where the output of one amplification stage is directly connected to the input of the next stage without the use of coupling capacitors or transformers. This direct connection allows both DC (direct current) and AC (alternating current) signals to pass from one stage to the next.

A Monolithic Direct-Coupled GaAs Amplifier with 12-GHz Bandwidth
IEEE Transactions on Microwave Theory and Techniques, 1984A two-stage feedback amplifier with direct connection between two stages has been developed for the 0.1- 12-GHz frequency band. The measured gain is 10+-1 dB with 2.5:1 input and 1.7:1 output VSWR. The measured minimum power output at 1-dB gain compression and maximum noise figure are 14 dBm and 9 dB, respectively, from 2 to 12 GHz.

Ultra-broad-band GaAs monolithic direct-coupled feedback amplifiers
IEEE Electron Device Letters, 1983GaAs monolithic direct-coupled amplifiers with load resistor and feedback resistor have been developed. The fabricated amplifier using the self-aligned implantation for n+-layer technology (SAINT) FET's has a 10-dB gain, a 7.2-dB noise figure, and input VSWR less than 2.0 over the frequency range from dc to 4 GHz.

GaAs IC Direct-Coupled Amplifiers
1980 IEEE MTT-S International Microwave symposium Digest, 1980Performance of six different direct-coupled GaAs IC amplifiers, with bandwidths up to 4.5 GHz, is described, along with that of one similar ac-coupled amplifier. Statistical data on gain, bandwidth, distortion, and noise is presented. The effectiveness of inductor peaking, resistive loads, and variable feedback is discussed.

Direct Coupled Detector and Amplifiers with Automatic Grid Bias
Proceedings of the IRE, 1928A system for direct coupling of vacuum tubes to give composite detection and amplification is described. The system is designed to avoid frequency discrimination in amplifying audio frequency, and to be free from electrical and acoustical feed-back effects.

An optical guided‐wave dye laser and directional coupling amplifier
Electronics and Communications in Japan (Part I: Communications), 1982AbstractThe properties of a new type active thin‐film optical waveguide with layers of Corning glass 7059, Pyrex, and Rh 6 G dye formed on a fused quartz substrate are discussed. It generates superradiant emission when excited by a pulsed N2UV laser. When the top layer is shaped as a square, resonant behavior is observed between the corner reflectors ...
