Abstract: A CMOS output buffer uses feedback from a ground node to reduce ground bounce by utilizing a tolerable ground bounce limit, making it less sensitive to operating conditions and processing parameters. An input to the NMOS device of the output buffer is provided by the output of a control element which receives a first input from a pre-driver and a second input (i.e., the feedback) from the ground node.

Abstract: A voltage level translator for digital logic circuits provides high level to low level voltage translation with equal rise and fall delays. The voltage level translator may include an input high voltage logic inverter (operating at the high voltage level) and connected to an output low voltage logic inverter operating at the low voltage level via a voltage reduction circuit. A related method for providing high level to low voltage translation may include providing an input inverter operating at the high voltage level and an output inverter operating at the low voltage level. Furthermore, the output of the high voltage inverter may be coupled to the input of the low voltage inverter after reducing the output voltage of the high voltage inverter to the required level.

Abstract: A circuit having a centralized PT compensation circuit to provide compensation signals to localized I/O blocks on the chip. Process variations and temperature variations tend to be approximately uniform across an integrated circuit chip. Thus, a single, centralized PT compensation circuit may be used instead of one PT compensation circuit per I/O section as with solutions of the past. Further, the PT compensation circuit may generate a digital code indicative of the effects of process and temperature. Further yet, each section of I/O block may have a local voltage compensation circuit to compensate the voltage variation of the I/O block. The voltage compensation circuit utilizes an independent reference voltage. The reference voltage is generated by the PT compensation circuit, which is placed centrally in the IC chip and hence any need to repeat the reference generation for each I/O block is eliminated.

Abstract: A GOP-independent dynamic bit-rate controller system includes a user interface to receive one or more input parameters, a bit-rate controller and an encoder. The bit-rate controller regulates a bit-rate of an output bit-stream. The bit-rate controller includes multiple bit-rate modules to determine a bit-estimate and a quantization parameter, and a control module to calculate a convergence period based on the received input parameters and a frame rate. The control module selects a bit rate module based on the convergence period and the encoder generates the output bit-stream using the quantization parameter determined by the bit rate module.
