US Patent:

7583108, Sep 1, 2009

Filed:

Mar 17, 2006

Appl. No.:

11/384013

Inventors:

Kevin Ryan - Colorado Springs CO, US

Assignee:

Aeroflex Colorado Springs Inc. - Colorado Springs CO

International Classification:

H03K 5/153

US Classification:

327 77

Abstract:

A current comparator includes an input node for receiving an input current, an output node, a first wide swing current mirror having an input coupled to the input node of the current comparator, a power node for receiving a first power supply voltage such as ground, and an output coupled to the output node of the current comparator, and a second wide swing current mirror having an input coupled to the input node of the current comparator, a power node for receiving a second power supply voltage such as VDD, and an output coupled to the output node of the current comparator. The output node can provide either a voltage or current output signal.

International Classification:

H03L 5/00
H03K 3/00

Abstract:

A high speed voltage translator circuit includes a voltage divider coupled between first and second power supplies, a transconductance amplifier coupled between third and fourth power supplies including a non-inverting voltage input coupled to the voltage divider, an inverting voltage input for receiving an input signal, and a current output, and a current comparator coupled between the third and fourth power supplies having an input coupled to the current output of the transconductance amplifier, and an output for providing a translated output voltage. The translated output voltage transitions between the third and fourth power supply voltage levels, the third power supply voltage level being more positive than a first power supply voltage level, and the fourth power supply voltage level being more negative than a second power supply voltage level.
