A Fully Integrated BiCMOS AM/FM Car Active Antenna with On-Board Battery Voltage Regulator
نویسندگان
چکیده
This paper presents an integrated AM/FM active antenna for car radio with on-board battery voltage regulator. The proposed system uses a minimum number of external components, thus reducing cost and increasing yield. The prototype fabricated in a 0.8 μm double-metal, double-poly BiCMOS process, consumes 30 mA from the 5 V regulated supply and exhibits an IP3 better than –60 dBc with two 100 dBμV tones at the output in both the AM and the FM bands. The voltage regulator is powered directly from the car battery voltage (9 16 V) and produces a stable 4.5 5.5 V supply voltage for the chip core, consuming 10 mA.

متن کاملLow Dropout Based Noise Minimization of Active Mode Power Gated Circuit
Power gating technique reduces leakage power in the circuit. However, power gating leads to large voltage fluctuation on the power rail during power gating mode to active mode due to the package inductance in the Printed Circuit Board. This voltage fluctuation may cause unwanted transitions in neighboring circuits. In this work, a power gating architecture is developed for minimizing power in a...
