The NMOS transistor (502) has a source-drain path provided in series with a PMOS transistor (505) serving to connect the current mirrors (151-154) and (155-158) and to eliminate input offset. The source of transistor (500) is separated from the VSS and VDD rails by a PMOS transistor ...
In addition, each operational amplifier in the chip has current limiting protection for the PMOS (high side) and NMOS (low side) output transistors, because overcurrent may be found on the high side or the low side. And two dedicated pins (as shown in the red box in the figure) are pr...
Current-feedback operational amplifiers is widely used in the high-speed and high-frequency electronic fields. A new style CFOA was proposed in this paper, the compensation circuit eliminate the imbalance between the two input in static condition,the PMOS and NMOS complementary input structure enhance...

In addition, it has low requirements on the performance of noise-shaping filters. The simple, low-order and even lossy filters can be employed since the SAR quantizer already provides relatively high raw resolution. In this way, the NS-SAR ADC can inherit the energy efficiency of SAR ADC by...
b Folded cascode OTA using resistive degeneration to reduce the noise influence of nMOS devices. Note that the current flowing through the biasing branch, Mb1-Mb3-Mb5-k × R1, is k times smaller than the tail branch of the amplifier. c band-pass (Tow-Thomas) filters for performing ...
and is an NMOS transistor. Thus, as the output voltage of the op-amp84rises, the current in transistor Mx1increases. Accordingly, the current though transistor Mx1increases as the current traveling out of the Vreg1output node (to the PLL10) decreases. Similarly, as the current traveling out...
