The peak voltage depending on the load current can be affected by external capacitors installed in output stage of LDO regulator. However, capacitor-less regulator proposed this study was applied a driving buffer structure between error amplifier and path transistor. Therefore, maintained stable regardless controlling an effective overshoot/undershoot voltage. In addition, has built-in LVTSCR b...

This paper presents an improved linearity variable-gain amplifier (VGA) in 0.18-µm CMOS technology. The lineari­ty improvement is resulted from employing a new combinational technique, which utilizes third-order-intermodulation (IM3) cancellation mechanism using second-order-intermodul­ation (­IM2) injection, and intermodulation distortion (IMD) sinking techniques. The proposed VGA gain cell co...
