چکیده

A novel adaptive current biased CLASS-A/shallow AB RF power ampli ̄er is demonstrated in this paper. By theoretical deduction, a prototype is described to improve the linearity of a linear PA. With the realization on Jazz 0:35 m SiGe HBT process and test veri ̄cation, the novel adaptive current biased RF power ampli ̄er shows 3 7 dB improvement of the ACPR at the output power of 19 dBm to meet the demand of CDMA IS95 spectrum mask without debasing the e±ciency.

An 8.4 GHz SiGe/Si HBT-Based MMIC Power Amplifier

A single-stage X-band MMIC power amplifier incorporating a SiGe/Si power HBT and lumped passive components is reported. The power HBT is characterized by an fmax of 67 GHz and a BVCBO of more than 24 V. The matching circuits were designed for maximum output power using on-chip spiral inductors and SiO MIM capacitors. Continuous wave measurements were made at 8.4 GHz, under class A operation. Th...

Physics and Modeling of Noise in SiGe HBT Devices and Circuits

This paper gives an overview of the physics and modeling of noise in SiGe HBT devices and circuits, including RF broadband noise, low-frequency noise, and oscillator phase noise. The ability to simultaneously achieve high cutoff frequency (fT ), low base resistance (rb), and high current gain (β) using Si processing underlies the low levels of low frequency 1/f noise, RF noise and phase noise o...
