This letter demonstrates a CMOS impulse radio ultrawideband (IR‐UWB) on–off keying (OOK) generator with multipulses per bit generation. The proposed IR‐UWB OOK generator is implemented in 0.11 μm CMOS process where 1.33 mm2 proto‐type accomplishes pulse train of 250 Mbps for one bit duration while consuming 10 mW from 1 V supply voltage. This pulse generator complies with the FCC spectral mask for...
This paper describes an IR-UWB OOK transmitter with multi-pulses per bit for bio-signal detectors which can be transplanted into the living body. The proposed IR-UWB OOK transmitter is implemented in 110 nm CMOS process where 1.33 mm2 proto-type accomplishes a maximum pulse rate of 250 Mbps while consuming 11 mW from 1 V supply voltage. It consists of impulse generator, LC oscillator, delay cell and...
We present a rectifier for wireless power transmission using multiplier configuration in layout for MOSFETs which works at 13.56 MHz, designed to fit in CMOS process where conventionally used diodes are replaced with the cross-coupled MOSFETs. Full bridge rectifier structure without comparators is employed to reduce current consumption and to be working up to higher frequency. Multiplier configuration...
In this paper, we propose a VCO using the negative resistance property of bump structure. The proposed VCO consists of a bump circuit and an LC resonator for obtaining high powers at the harmonic frequencies. The VCO is designed in 0.13μm RF CMOS process. The VCO works at the center frequency of 3.35GHz with −2.1dBm output power while this circuit consumes 20mW with 1.2 V supply. Due to the negative...
