Introduction: On-chip integrated circuits often need to be tunable to correct for process or temperature variations. However, unpredictable or unknown device characteristics make it hard to implement tunable linear circuits. In modern submicron CMOS technologies, the transistor characteristics can deviate significantly from the ideal behaviour. In this Letter a continuously tunable current divi...

This paper proposes compensated methods to cancel the effects of charge injection error on switched-current Divider Circuits. Algorithmic structures of current dividers are presented and the final charge injection error is evaluated for each Algorithm. So, compensated methods to cancel this error are proposed.

A fully integrated low-IF receiver for 1.8GHz in 0.13-μm CMOS is presented. The receiver consists of a VCO, an IQ-divider, an LNA, and a double balanced IQ-mixer. The RF input stage and the commutating stage of the IQ-mixer are current coupled via an on-chip transformer which is operating in resonant mode and is performing a current gain. A design method is presented to reduce the input impedan...

In this paper, nonlinear-carrier (NLC) control is proposed for high-power-factor rectifiers based on flyback, Cuk or Sepic converters operated in the continuous conduction mode. In the NLC controller, the switch duty ratio is determined by comparing a signal proportional to the integral of the switch current with a periodic nonlinear carrier waveform. The shape of the NLC waveform is determined...

The application of sliding mode, a non-linear robust and self-contained approach, to the control problem of electronic power converters, is outlined and illustrated. On-line sliding mode control is suited to multilevel power converters as they are inherently variable structure systems. Obtained controllers are robust concerning parameter variation and perturbations and provide "Just In Time" sw...

In this paper, nonlinear-carrier (NLC) control is proposed for high-power-factor rectifiers based on flyback, Ćuk, Sepic, and other up–down converters operated in the continuous conduction mode (CCM). In the NLC controller, the switch duty ratio is determined by comparing a signal proportional to the integral of the switch current with a periodic nonlinearcarrier waveform. The shape of the NLC ...

In this paper we are presenting novel current multiplier/divider circuits utilizing the power of FGUVMOS transistors. Even for ultra low supply voltages a proper operation is achieved with threshold shifting using post-fab. tuning. Measured results are provided of a multiplier working over a large magnitude in current at 0.7V power supply.

In this paper, the closed-form design method of an Nway dual-band Wilkinson hybrid power divider is proposed. This symmetric structure including N groups of two sections of transmission lines and two isolated resistors is described which can split a signal into N equiphase equiamplitude parts at two arbitrary frequencies (dual-band) simultaneously, where N can be odd or even. Based on the rigor...

A new multiplier-divider circuit using a single Current Differencing Buffered Amplifier (CDBA) and only six MOSFETs has been presented. The proposed circuit has the advantage of simultaneously realizing a multiplier and divider without changing the circuit topology. The basic functions of the proposed circuit have been verified through PSPICE simulations using a CMOS CDBA and NMOS transistors w...
