  • Bipolar stacked transistor architecture
    Patent number: 8791759
    Abstract: An amplifier for an integrated circuit has a plurality of ratioed current mirrors connected to each other in a stacked configuration. Each ratio mirror has at least two resistors and at least two bipolar transistors connected to each other via said at least two resistors. Each amplifying transistor, contains a capacitor, and potentially and inductor, to internally match the transistors that make up the amplifying stack. DC, harmonic and s-parameter simulations are performed to provide an optimal impedance for each of the stacked transistors to maximize the RF power output of each stacked layer and the amplifier.
    Type: Grant
