Abstract :
A BIMOS AM front-end amplifier mixer is discussed. The advantages of BIMOS technology in the realisation of front-end amplifiers is demonstrated. Because of the low-voltage power supply, bipolar transistors are required for the mixer structure. It is shown that for low-noise applications an MOS input structure results in a better performance. The stability problem of a bipolar and MOS input structure is also analysed. It is shown that the MOS input structure has a better stability performance
