  • Patent number: 4841253
    Abstract: A monolithic semiconductor having an on-chip DC biasing including a plurality of series connected spiral inductors connected between the respective biasing and the semiconductor circuit. The spiral inductors provide a low resistive path for the DC biasing while also having a high inductance for isolating the RF signal from the bias sources, thereby improving the low frequency response. The capacitance associated with the individual spirals, however, is significantly less than the capacitance associated with a single spiral inductor having an equivalent inductance of the small series connected spirals; thus the higher frequency response is not degraded while the low frequency response has been improved.
