AN-035_-_Gain_Block_Active_BiaDESIGN APPLICATION NOTE --- AN035
Gain Block Active Bias Circuit Abstract Gain Block amplifiers (SGA,NGA,SNA,SCA series) sometimes require power supply voltages very close to the rated device voltage. This provides a challenge to stabilize current with temperature and device-to-device bias voltage variations. A cost effective and power efficient solution to this problem is discussed here. Introduction In order to obtain stable bias current and consistent RF performance using gain block amplifiers, SMDI recommends that customers normally use a dropping resistor in series with the power supply voltage so that a minimum 2 Volt drop is maintained across it. This circuit configuration is shown in Figure 1(a). To emphasize the temperature dependence of Vd, it is represented in the expression for……
