This paper proposes a circuit capable of incorporating buffered delays in the order of picoseconds. To study our proposed circuit in the profound way, we have also explored our proposed circuit using emerging technologies such as FinFET and CNFET. Comparisons between these technologies have been made in terms of different parameters such as duration of incorporated delays (pulse width) and its variability with supply voltages. Further, this paper also proposes a trigger pulse generator by utilizing proposed buffered delay circuit as its basic element. Parametric results obtained for the proposed trigger pulse generator match different application specific requirements. These applications are also mentioned in this paper. The proposed trigger pulse generator requires very low supply voltage (700 mV) and also proves its effectiveness in terms of tunability of pulse width of the generated pulses. The modeling of the circuit has been done using Verilog and the simulation results are extensively verified using SPICE.

In this paper, a variable gain amplifier (VGA) designed in 130 nm CMOS technology is presented. The proposed amplifier is based on the bulk-driven (BD) design approach, which brings a possibility to operate with low supply voltage. Since the supply voltage of only 0.6 V is used for the amplifier to operate, there is no risk of latch-up event that usually represents the main drawback of the BD circuit systems. BD transistors are employed in the input differential stage, which makes it possible to operate in rail-to-rail input voltage range. Achieved simulation results indicate that gain of the proposed VGA can be varied in a wide scale, which together with the low supply voltage feature make the proposed amplifier useful for low-voltage and low-power applications. An additional circuit responsible for maintaining the linear-in-decibel gain dependency of the VGA is also addressed. The proposed circuit block avails arbitrary shaping of the curve characterizing the gain versus the controlling voltage dependency.

Simulation results illustrate that there is an optimum-energy supply voltage point (Vopt) for SoC. And these voltage points normally lie in weak sub-threshold or near-threshold region. Considering about the degraded robustness under this low supply voltage, structural change instead of the sizing change is considered in proposed design. Different from conventional 6T SRAM design, the trip point voltage of proposed design changes according to bit-line voltage values. In this way, its read margin is 45% greater than conventional 6T SRAM. The proposed bit-cell exhibits wide hysteresis effect, making the design less vulnerable to process variation. Its hold margin is 30.2% greater than conventional 6T SRAM. The optimum-energy supply voltage of proposed array (256×16) is 400 mV. At the same time, the power consumption at 400 mV decreases to 16% compared to that at 1200 mV.

This paper presents ultra-low voltage transconductor using a new bulk-driven quasi-floating-gate technique (BD-QFG). This technique leads to significant increase in the transconductance and the bandwidth values of the MOS transistor (MOST) under ultra-low voltage condition. The proposed CMOS structure of the transconductor is capable to work with ultra-low supply voltage of ±300 mV and low power consumption of 18 μW. The transconductance value of the transconductor is tunable by external resistor with wide linear range. To prove the validation of the new described technique a second-order Gm-C multifunction filter is presented as one of the possible applications. The simulation results using 0.18 μm CMOS N-Well process from TSMC show the attractive features of the proposed circuit.

The conventional shift register consists of master and slave (MS) latches with each latch receiving the data from the previous stage. Therefore, the same data are stored in two latches separately. It leads to consuming more electrical power and occupying more layout area, which is not satisfactory to most circuit designers. To solve this issue, a novel cross-latch shift register (CLSR) scheme is proposed. It significantly reduced the number of transistors needed for a 256-bit shifter register by 48.33% as compared with the conventional MS latch design. To further verify its functions, this CLSR was implemented by using TSMC 40 nm CMOS process standard technology. The simulation results reveal that the proposed CLSR reduced the average power consumption by 36%, cut the leakage power by 60.53%, and eliminated layout area by 34.76% at a supply voltage of 0.9 V with an operating frequency of 250 MHz, as compared with the MS latch.

This work presents a single chip integrated pulse generator-modulator to be utilized in a short range wireless radio sensors remote control applications. The circuit, which can generate single pulses, modulated in BPSK, OOK, PAM, and also PPM, has been developed in a standard CMOS technology (AMS 0.35 μm). Typical pulse duration is about 1 ns while pulse repetition frequency is until 200 MHz (5 ns "chip" time). The operating supply voltage is ± 2.5 V, while the whole power consumption is about 15 mW. Post-layout parametric and corner analyses have confirmed the theoretical expectations.
