A novel voltage delta IDDQ test method is presented for circuits working in low voltages. The proposed method can eliminate the any contribution from leakage due to the usage of differential IDDQ test method. The proposed method is successfully implemented on 1-bit, 32-bit and 100-adders circuits on IBM 130 nm technology and can detect faulty circuit only if short is activated from the applied ...
Low-voltage high-speed switched-capacitor (SC) circuit design without using voltage bootstrapper is presented. The basic building block used for low-voltage SC circuit design is the auto-zeroed integrator (AZI), which can work at both low voltage and high sampling frequency. With this method, two low-voltage SC systems were successfully designed and implemented in 1.2m CMOS technology. The firs...
A low-voltage, low-power analog multiplier operating at 1.2 V is presented. The multiplier i,s composed of a pair of voltage-to-current converters and a pair of voltage followers. The current produced is then added in resistors to produce the voltage output. The circuit rnultiplies the incoming 900 MHz RF signal with an 800 MHz local oscillator signal to produce a 100 MHz IF output. The circuit...
Different cascode circuits are investigated with regard to their suitability for low-voltage and low-current circuits. A generalized circuit representation is introduced and different cascode circuits are discussed with respect to their small-signal parameters as well as their associated dynamic output ranges. The output voltage ranges for saturation operation of the different cascode circuits ...
An ultra-low voltage phase-locked loop (PLL) is demonstrated in standard 130-nm CMOS technology. The PLL employs a novel low-voltage charge-pump circuit which compensates current and leakage mismatches that result in suppressed reference spurs. Its voltage-controlled oscillator is realized with supply-regulated active-loop filter. Our PLL occupies 0.014 mm and consumes 88 μW at 0.4-V supply for...

⎯A novel CMOS atto-ampere current mirror (AACM) is proposed which reaches the minimum yet reported current range of 0.4 aA. Operation of this circuit is based on the source voltage modulation instead of the conventionally used gate voltage modulation which interestingly prevents usage of commonly required voltage shifting in those circuits. The proposed circuit has a simple structure prohibitin...
This paper proposes a CMOS low-power low-voltage microphone preamplifier for a cochlear implant system. The proposed preamplifier using the Flipped Voltage Follower Current Sensing (FVFCS) technique to achieve low voltage, low power consumption. The proposed circuit was designed and simulated using a 0.35 m CMOS process. Simulation results showed that the preamplifier can achieve 22-dB voltage ...
A process, voltage and temperature (PVT) sensors with dynamic voltage selection are proposed for environmental management in the ultra-low voltage dynamic voltage and frequency scaling (DVFS) system. The process and voltage (PV) sensors initially monitor the process variation. With known process information, PV sensors can real-time provide voltage variation status. The temperature sensor has s...
