Non-conventional architectures that enable optimizing the power consumption in a second-order or an equivalent second-order scheme are proposed. The solutions exploit the significant difference in power consumption of comparators and OTAs that makes it advantageous to use more comparators to replace an OTA. Moreover, the use of op-amp time-sharing is discussed. For this a conventional second or...

A novel class-AB transconductance amplifier, suitable for the input stage of high slew rate CMOS operational amplifier is proposed. The proposed class-AB transconductor is realized from a differential pair of mixed translinear common-drain push-pull circuit. A high speed operational amplifier employing the proposed input stage and a complementary common –source high gain stage is presented. HSP...

A proposed third order noise shaping accelerometer interface circuit enhances the SNR compared with the previ ously presented interface circuits The solution for the two chip implementation is described and a novel cross coupled CDS integrator is proposed This scheme functions even with the large parasitic capacitances between the sensor and the interface circuit The op amp noise is rst order s...

The presented work deals with analysis of non-ideal effect of pipelined analog-to-digital converter (ADC) such as random capacitor mismatch, comparator offset and finite op-amp gain. These factors arise during a conversion in the pipelined ADC when using CMOS technology and switched-capacitors (SC) technique. The pipelined ADC was simulated in MATLAB-Simulink simulation environment. Key-Words: ...

• The on-chip op amp of the PIC16F785 is used to amplify the voltage across the current sensing resistor. This allows a much smaller sensing resistor to be used and reduces power dissipation. • The PIC16HV785 device can be used, which eliminates the requirement for an external 5V regulator when operating from higher supply voltages. • This application has unused analog resources which could be ...

This paper presents a comparison study on influences of on-chip electro-static discharge (ESD) protection structures on performance of the circuits protected, using 1.5V, 0.18μm aluminum and copper interconnect technologies, respectively. A low-power, high-speed Op Amp was designed. Simulation results show that while ESD parasitics may degrade the circuit performance inevitably, the use of Cu i...

The very fast growing market of portable equipment is increasing interest in low power integrates circuit. So, designing low power integrated circuits requires reduction of supply voltages and interconnection parasitic to minimum but reduction in supply voltage implies series of problems in circuit design. To overcome these issues, an Ultra low power low voltage two stage class AB CMOS fully di...
