High Output Impedance Current Source

This current source uses a reference current and produces an output current that has substantially higher dynamic output impedance, particularly for low current levels of less than 100uA. This current source buffers the reference current and produces a constant current for a wide voltage range. This current source utilizes two pairs of N channel matched pair MOSFETs connected in a cascode configuration. The bottom MOSFET pair must be a matched pair and the top MOSFET pair must also be a matched

AN1033 Match Impedances in Microwave Amplifiers

The key to successful solid-state microwave power-amplifier design is impedance matching. In any high-frequency power-amplifier design, improper impedance matching will degrade stability and reduce circuit efficiency. At microwave frequencies, this consideration is even more critical, since the transistor's bond-wire inductance and base-to-collector capacitance become significant elements in input/output impedance network design. In selecting a suitable transistor, therefore, keep in mind th
