  • Abstract
    SiGe HBTs featuring a high quality oxide passivation show ideal Gummel plots and low 1/f noise with corner frequencies down to 300 Hz. The measured KB-factor of 2.6×10-10 μm 2 s is the lowest of any previously reported HBT. With an f T of 40 GHz, the devices are ideal for low phase noise microwave oscillators. A simple 10 GHz microstrip resonator showed -100 dBc at 100 kHz off carrier
