This paper presents a nano-watt bandgap voltage reference (BGR). The self-cascode structure is provided as proportional-to-absolute-temperature (PTAT) voltage. Due to the low slope of PTAT voltage, divider consisting five similar MOSFET transistors presented. resulting output will be one-fifth complementary-to-absolute-temperature and four-fifths All MOSFETs are standard CMOS biased in sub-thre...

The design of A 2.4-GHz CMOS Class E cascode power amplifier (PA) for GSM applications in TSMC 0.18-μm CMOS technology present in this paper. Proposed Class E cascode PA topology is a single-stage topology in order to minimize the device stress problem. A parallel capacitor is connected across the transistors for efficiency enrichment also for dominating the effect of parasitic capacitances at ...

Now a day’s demand of portable devices like multimedia devices, cellular phones, etc. are increasing and we are approaching towards handheld devices which are small in size and which requires large battery life. Power consumption has become most important design factor for VLSI circuits and system in low power devices. The Level shifter plays very critical role in low power devices. Level shift...

This work proposed a low power and high gain folded cascode CMOS operational amplifier with a common mode feedback (CMFB) for Pipeline ADC. The proposed design is implemented in 0.13-μm Silterra CMOS technology. The folded cascode topology has been used for obtaining a high gain and low power consumption. Meanwhile, the CMFB is modified circuit to be a double detection to stabilize the output o...

The charge-pump circuit is an important component in a phase-locked loop (PLL). The charge-pump converts Up and Down signals from the phase/frequency detector (PFD) into current. A conventional CMOS charge-pump circuit consists of two switched current sources that pump charge into or out of the loop filter according to two logical inputs. The mismatch between the charging current and the discha...
