| Abstract | (in Japanese) | (See Japanese page) |
| (in English) | Recent advances in the process technology of electronics devices have opened the possibility of achieving submillimeter-wave imaging sensors and wireless communication systems. As low noise amplifiers (LNA) are placed at the receiver’s front-end, wide-bandwidth, high-gain and low-noise characteristics are required. In this reports, submillimeter-wave amplifier design methodologies in 75 nm InP HEMTs are reported. Three-stage common-gate amplifiers realizes gains of, 15 dB for D-band, and 10 dB for G-band band by changing output matching inductor of unit amplifier. Moreover, a high gain amplifier is generally difficult to realize in these frequency range, because unwanted feedback power cause unstable operation. Our proposed feedback reduction architecture successfully achieved 30 dB gain at around 230 GHz. A modulator and an envelope detector are also implemented in the amplifier to confirm a large signal operation. Clear eye-opening waveform from the detector output can be successfully obtained for 10 Gb/s data signal. | |
