A Switched Capacitor Cmos Voltage Reference For Ultra Low

Max660 for the lmc7660 switched capacitor voltage converter.

Switched capacitor voltage reference. The output characteristics of this circuit can be approximated by an ideal voltage source in series with a resistor. The max1044 and icl7660 are monolithic cmos switched capacitor voltage converters that invert double divide or multiply a positive input voltage. We have developed a switched capacitor cmos voltage reference scvr.

A switched capacitor cmos voltage reference for ultra low voltage and ultra low power operation abstract. A compact switched capacitor regulated charge pump power supply b. Low output is produced through capacitive subdivision instead of the resistive subdivision used in 11 and nano power dissipation can be achieved.

An adaptive switch driver scheme optimizes efficiency over a wide range of. De vita and g. A high eciency and extremely low ripple buck converter is designed using a switched capacitor voltage divider which converts 33 v down to 15 v while operating at a switching frequency of 15 mhz and a load current range of 10ato 1 ma.

Switched capacitor voltage converter with regulator the lt1054 is a monolithic bipolar switched capacitor voltage converter and regulator. A cmos based switched capacitor voltage reference scvr 20 is proposed to improve the design in 6. Operation is guaranteed from 15v to 10v with no external diode over the full temperature range.

Iannacone 2007 a core circuit and a switched capacitor difference amplifier that is insensitive to op amp offset voltage. Given that fact a temperature stable current can be developed using a switched capacitor. The lt1054 provides higher output current than previously available converters with significantly lower voltage losses.

3 current reference architecture precise crystal based clocks and temperature independent voltage references are commonly available on chip. Robert gregoire member ieee abstracta cmos switched capacitor reference is combined with a switched capacitor voltage doubling charge pump to pro duce a compact regulated 32 v power supply from an input that ranges from 18 to 35 v. It can supply up to 6 ma at minimum input.

The circuit is shown in fig. The voltage source equals v. The zsc switched capacitor converter features a two stage architecture for 48v applications to power cpus gpus asics socs and memory.

They are pin compatible with the industry standard icl7660 and ltc1044. Infineon technologies ag introduced its zero voltage switching zsc switched capacitor converter reference design. An ultra low voltage and low power cmos voltage reference using subthreshold body effect and switched capacitor techniques is proposed in this paper.
