We propose a novel non-classical complementary metal oxide semiconductor (CMOS) inverter, which is composed of a Gated control NNP for driver N-type transistor (Gated-NNP) and a Gated control PPN for load P-type transistor (Gated-PPN). These two transistors have the same doping architecture with tunnel field effect transistor (TFET), but not use tunneling current mechanisms to achieve complementary...
This paper discusses mm-wave CMOS transceiver IC design focusing on the techniques to increase the transmission data rate. Basic design key points are the increase of bandwidth, the increase of SNR, the decrease of phase noise in quadrature oscillator and frequency interleaving technique. Thus we selected the direct conversion architecture with resistive feedback amplifier to realize the wideband...
A low phase noise voltage-controlled oscillator for mm-wave applications is presented. The oscillator uses switched-capacitor technique to increase the tuning range. The measured results show that the oscillator achieves a phase noise of −100dBc/Hz at 1MHz offset from the carrier frequency of 49.7GHz, while consuming 5.5mA current from a 0.9V supply. A wide tuning range percentage of 12%, i.e. 43...
A new realization of a Voltage Controlled Oscillator (VCO) is introduced, and the description of its properties is provided. It is shown that this new realization offers several advantages in comparison with conventional VCOs and can be useful in certain design applications. Theoretical derivations and implementation are presented.
The TSV(Through-Silicon Via) plays an important role of inter-layer interconnection in 3D ICs. However, TSV is defect prone. This paper proposes a new scheme based on oscillator to monitor the defects of TSV at the prebond stage.
On the basis of PWM-based peak current sampling DC-DC converter, the circuit uses superimposition of sampling signal and slope compensation signal, and consists of peak current sampling amplifier, slope compensation circuit, and superimposition circuit. The peak current sampling amplifier converts current sampling signal into current and then inputs it onto superimposition circuit. The slope compensation...
In order to solve the disadvantages of Leeson model in studying the phase noise of quartz crystal oscillator, an optimized model for integrated quartz crystal oscillator was established by decomposing the whole circuit into the amplifier module and the resonator module. Subsequently, simulation was carried out by Cadence to verify the optimized model. According to the optimized model, at ƒc=20MHz,...
This paper presents a low-power area-efficient instrumentation amplifier (IA) for biopotential recording. The proposed IA adopts a resistor-controlled-oscillator (RCO) to change the mid-band gain of the readout circuit for different biomedical applications. The switched-capacitor load of the IA changes with RCO's output frequency, making the gain of IA continuous tunable. Measurement results show...
