چکیده
| A new current-mode, low-power, lowvoltage and high-speed CMOS sample-and-hold circuit has been designed and fabricated. A new currentmode di erential switching scheme has been adopted to eliminate errors caused by feedthrough injection from the sample switches. The experimental result yields 9-bit resolution in 9mW power dissipation, in a 20MHz clock frequency from a 3V power supply.

متن کاملA Current-Mode Circuit With a Linearized Input V/I Conversion Scheme and the Realization of a 2-V/2.5-V Operational, 100-MS/s, MOS SHA
This paper proposes a circuit to linearize the signal current and improve the distortion characteristics at the input of a current-mode circuit. Input voltage-to-current (V/I) conversion is carried out by a resistor that connects the signal source and the current input terminal of the current-mode circuit. The signal current flowing into the current-mode circuit through this resistor is distort...

This paper describes an MOS current-mode sample-and-hold (S/H) circuit that potentially operates with a sub-1.5 V supply voltage, 20 MHz clock frequency, and less than 0.1% linearity. A newly developed voltage-to-current converter suppresses the voltage change at an input terminal and achieves low-voltage operation with superior linearity. Sample switches are differentially placed at the inputs...

A high-linearity and high-speed current-mode sampleand-hold circuit is designed and simulated using a 0.25μm CMOS technology. This circuit design is based on low voltage and it utilizes a fully differential circuit. Due to the use of only two switches the switch related noise has been reduced. Signal dependent -error is completely eliminated by a new zero voltage switching technique. The circui...
