    Looking for some assistance in the design of a Class B power amplifier. This is the final stage in a servo system. The power amplifier drives a motor whose coil resistance is typically less than 2 ohms and around 100 microhenry. The power amplifier is supplied typically with + and - 24V. It works but needs some tuning. So we're looking for someone with circuit simulation experience, and with experience optimizing power amplifier output stages.

    I'm exploring a new project that will require the development of a passive rfid tag capable of being read over a distance of between 5cm and 100cm by a mobile phone. The tag will be used in clothing and so needs to be water proof / heat resistant and wearable. I have found a tag by Fugitsu which looks ideal but I need the tag to be readable by a mobile phone not an independent tag reader (Fuji tag datasheet ...
