Manufacturer:ALTERA Description:II. Circuit Design A schematic of the two-stage LNA is shown in Fig. 1. The circuit employs a high-gain common-emitter stage (Q1-RL) and a emitter-follower output stage (Q2-Q3). This approach eliminates the need for coupling capacitors. The current of the first stage is set by a resistive parallel feedback (R3 and R4), which is connected to the external matching inductor (L1) such that no noise degradation occurs. Thus, only a single supply voltage is required. This feedback also improves both the bias and RF stability of the amplifier. |
