The conventional one-cycle control (OCC) technique requires the integrator to reset instantaneously. However, it is very difficult to realize by hardware due to the finite time constant of a reset circuitry, which loads to a large DC offset in the output voltage. Therefore, the paper presents a new control scheme to resolve the problem, which is based on considering a singlephase full-bridge inverter...
This paper presents the multi-band inductor with 0.18 μm CMOS technology on plastic achieves high Q-factor and small size for multiband applications. The multi-band inductor on VLSI-standard Si Substrate is operated at ultra-wide band range. The operation frequencies are near 3 GHz, 4 GHz, 7.5 GHz and 9 GHz of the Q-factor are 6.5, 6.7, 8 and 11.5 with the inductance 2.1, 1.6, 1.1, 0.6 nH, respectively...
A low phase noise, small power dissipation and small sized K-band cascode differential voltage-controlled oscillator (VCO) with capacitive feedback topology using 0.18 μm CMOS technology is described. The VCO operated can be tuned between 19.1 GHz and 20.9 GHz and has low phase noise of -108.67 dBc/Hz at a 1 MHz offset. The output power of the 20.7 GHz is about -21.12 dBm. The Figure of merit (FOM)...
Wireless interconnection within a hybrid engine controller board has been demonstrated by demodulating an AM signal transmitted with an on-chip antenna using a receiver located in the board. The receiver centered between 14 and 16 GHz uses a Schottky diode detector and should be able to support 400-Mbps data rate and ~15 cm range. The receiver does not require a crystal frequency reference. The measured...
An RF transceiver for operation near 24 GHz with an onchip antenna, fractional-N synthesizer and other RF and analog baseband circuits is demonstrated in 130-nm CMOS. A 5-m wireless link was demonstrated using a transceiver pair. A technique for wireless calibration of an on-chip frequency reference is also demonstrated.
