Open loop controller uses innovative architecture

8 May 2002 Analogue, Mixed Signal, LSI

Xicor's new THOR architecture is designed for high performance open loop control. This allows designers to easily implement arbitrary 'nth order' error correction for True-Zero error systems. Errors related to time, temperature or other system level effects can be corrected in manufacturing, or adaptively, while the system is in operation. It features an 8-bit ADC input stage that can sample analog signals from external sources, or from either an on-chip programmable voltage reference or on-chip temperature sensor. An arbitrary compensation curve is stored in a 2176-bit on-chip look-up table. This digitised input signal is then multiplied by this stored information; the result then used to control either of two programmable current source outputs. The first THOR product, the X9530, is targeted at MANs and 10GE LANs. Other significant applications will be PIN-diode biasing in microwave comms systems, PWM control in DC motors, and PLL control in industrial servo control systems.
