The exponential rise in the density of silicon CMOS transistors has now reached a limit and threatening to end the microelectronics revolution. To tackle this difficulty, group III–V compound semiconductors due to their outstanding electron transport properties and high mobility are very actively being researched as channel materials for future highly scaled CMOS devices. In this paper, we have...

A complementary bipolar low-power, high-speed, current-feedback operational amplifier is described. The amplifier incorporates a new Class AB output stage that enables high output current drive of 100 mA and large voltage swing within 1 V of the supply rails while operating at low quiescent current of 1.5 mA. The amplifier was fabricated in a junction-isolated complementary bipolar process with...

This work presents an ultra-low-voltage ultra-low-power weak inversion composite MOS transistor. The steady state power consumption and the linear swing signal of the composite transistor are comparable to a single transistor, whereas presenting very high output impedance. This work also presents two interesting applications for the composite transistor; a 1:1 current mirror and an extremely lo...

Generally, bipolar transistors have better performance than MOS transistors if higher transconductances for the same operating point or higher transition frequencies are required. On the other hand, compared to MOS transistors, bipolar transistors often have limited use in the design of VCO’s, due to a limited voltage swing across the resonator and therefore limited phase-noise performance. How...

Low-voltage, low-power and medium-accuracy analog-to-digital converters (ADCs) are essential components in portable devices. Low-voltage operation of these ADCs poses three major challenges. First, the floating switches required in conventional switched-capacitor implementations are not operational for very low supply voltages. Second, reduced supply voltage translates to reduced signal power, ...

A double sampling technique adopted, which allows high opera...

This paper presents a monolithic three-axis accelerometer with wafer-level package by CMOS MEMS process. The compositions of the microstructure are selected from CMOS layers in order to suppress the in-plane and out-of-plane bending deflection caused by the residual stresses in multiple layers. A switched-capacitor sensing circuit with a trimming mechanism is used to amplify the capacitive sign...

In this paper a 17 bit monotonic precise current DAC for sensor applications is described. It is working in a harsh automotive environment in a wide temperature range with high output voltage swing and low current consumption. To guarantee monotonicity current division and segmentation techniques are used. To improve the output impedance, the accuracy and the voltage compliance of the DAC, two ...
