A bipolar high precision voltage-to-frequency converter is described. The circuit includes an input voltage-to-current conversion stage followed by a current-controlled multivibrator. The multivibrator trigger includes a window comparator with a limiter of the output voltage swing, and the timing capacitor discharge current is switched simultaneously with the window comparator bias. This allows...

A CMOS inverting type second generation current conveyor ‘positive’ (ICCII+) is presented which is based on voltage and current mirror circuits. PSPICE simulation results of the proposed structure using 0.5 μm MIETEC CMOS process parameters show that it is suitable for wideband applications and has got a wide output current swing with small current tracking error.

A low-voltage low-power CMOS operational transconductance amplifier (OTA) with near rail-to-rail output swing is presented in this brief. The proposed circuit is based on the current-mirror OTA topology. In addition, several circuit techniques are adopted to enhance the voltage gain. Simulated from a 0.8-V supply voltage, the proposed OTA achieves a 62-dB dc gain and a gain–bandwidth product of...

We utilized laser irradiation as a potential technique in tuning the electrical performance of NiOx/SiO2 thin film transistors (TFTs). By optimizing fluence and number pulses, TFT was evaluated terms mobility, threshold voltage, on/off current ratio subthreshold swing, all which were derived from transfer output characteristics. The 500 pulses-irradiated exhibited an enhanced mobility 3 cm2/V-s...

Introduction: Current-mode logic (CML) circuits are widely used in many high-speed and high-performance applications [1]. The differential topology of CML circuits provides high immunity to supply noise and crosstalk, while reduced voltage swing at the output helps to operate the circuit in very high frequencies with low noise generation [1, 2]. These properties make the MOS CML (MCML) topology...

Analytical models for channel potential, threshold voltage, and subthreshold swing of the short-channel fin-shaped field-effect transistor (FinFET) are obtained. The analytical model results are verified against simulations and good agreements are observed. Analytical expressions for subthreshold swing, drain induced barrier lowering effect, and threshold voltage roll-off characteristics are pr...

Clock signal has the highest switching activity and can be responsible for up to 40% of the overall power dissipa...

A new output structure for class E power amplifier (PA) is proposed in this paper. A series LC resonator circuit, tuned near the second harmonic of the operating frequency is added to the output circuit. This resonator causes low impedance at the second harmonic. The output circuit is designed to shape the switch voltage of the class E amplifier and lower the voltage stress of the transistor. T...

Serial link transmitters which efficiently incorporate equalization, while also enabling fast power-state transitioning to leverage dynamic power scaling, are necessary to meet future systems’ I/O requirements. This paper presents a scalable voltage-mode transmitter which offers low static power dissipation and adopts an impedance-modulated 2-tap equalizer with analog tap control, thereby obvia...
