Custom MMIC First to Discuss Positive Bias Sequencing at IMS

In comparison to depletion mode amplifiers, which require a bias sequencing circuit that ensures the negative gate voltage is applied before Vdd, enhancement mode amplifiers developed by Custom MMIC allow Vdd to be applied at any time with no current draw until the enable line is energized. In addition to removing the complex bias sequencing circuitry, the all-positive bias approach also eliminates the possibility of running the device open channel, a scenario that can easily damage or destroy depletion mode amplifiers. Finally, the positive bias scheme allows for pulsed mode operation at high speeds due to the low capacitance of the control line.

Custom MMIC has utilized the positive bias approach in a number of different standard products including distributed amplifiers, power amplifiers, low noise amplifiers, and ultra low power dissipation amplifiers.
