This paper presents a simple Pico Watt reference circuit with the output voltage of 263.1 mV using sub-threshold operation of MOSFETs at supply voltage of 0.7 V. Proposed circuit consumes merely 400 pW of power at room temperature and it is designed using standard TSMC 0.18 μm technology. Reference voltage is provided by subtracting the 0 • C threshold(More)
In this paper, a new in-package high efficiency voltage down converter (VDC) is presented. Usually, quality factor of induc-tors is the main problem for generating high efficiency DC-DC Converters. In order to mitigate this problem, Bonding Wires with a new form are exploited in which four mutual inductions of bonding wire are used to increase the total(More)
A fast settling multipath CMOS OTA for high speed switched capacitor applications is presented here. With the basic topol-ogy similar to folded-cascode, bandwidth and DC gain of the OTA are enhanced by adding extra paths for signal from input to output. Designed circuit is simulated with HSPICE using level 49 parameters (BSIM 3v3) in 0.35 um standard CMOS(More)
The present work deals with 12-bit Nyquist current-steering CMOS digital-to-analog converter (DAC) which is an essential part in baseband section of wireless transmitter circuits. Using oversampling ratio (OSR) for the proposed DAC leads to avoid use of an active analog reconstruction filter. The optimum segmentation (75%) has been used to get the best DNL(More)
