20150214897 | FAMILY OF SLEW-ENHANCED OPERATIONAL TRANSCONDUCTANCE AMPLIFIERS - Operational transconductance amplifiers (OTAs) with enhanced slew rate are disclosed. An OTA can have a main amplifier and pre-amplifier gain stage to increase the effective transconductance and bandwidth of the OTA. The pre-amplifier and main amplifier can be coupled to enhance slew current without adding additional bias current to the main amplifier input stages. Pre-amplifier bias current can be recycled and redirected to the load. OTAs with enhanced slew rate can be particularly useful in applications requiring high-frequency switching of voltage levels to drive high capacitance lines. For example, an integrated touch sensor panel and display can be operated by alternatively applying a first voltage level to an electrode in a display mode and a second voltage level during a touch sensing mode using OTA sense or charge amplifiers with enhanced slew rate. Enhanced slew rate can increase the time available to demodulate a touch signal for improved system performance. | 07-30-2015 |
