Abstract :
This paper presents a new high performance 1.2 V-0.18 μm CMOS differential voltage-to-frequency converter (dVFC). The proposed dVFC works properly over the whole differential input range providing an output frequency range of 0.0-0.9 MHz with 0.015% linearity error for a -40 to 120°C temperature range and a 30% supply voltage variation. Power consumption is below 60 μW, which makes it suitable to be used in portable applications.
