    摘要: An analog recording and playback system using non-volatile flash memory. An array of flash memory cells is used to store an analog signal and retrieve the stored analog signal on a real-time basis. A plurality of column driver circuits are coupled to the columns of flash memory cells for simultaneous programming and reading. A programming algorithm is used to write the analog signal within an operating range of the flash memory cells since the operating range may shift due to process variations. The system includes trimbit circuits to provide a trimmable initial programming voltage, programming step, programming current, read current, and select gate voltage. The system further includes a Serial Peripheral Interface ("SPI") that interfaces with a host microcontroller. The host microcontroller can send a number of commands to the system through the SPI for efficient message management. These commands include the basic commands to record or playback and various addressing and message cueing options. The system utilizes row and column redundancy to increase production yield.

    摘要: A power efficient high output swing operational ("HOOP") amplifier for integrated circuit analog signal processing is described. The operational amplifier includes a differential input stage and an output stage. The differential input stage is powered by a regular power supply while the output stage is powered by a voltage multiplier which results in a high voltage output swing without sinking significant power from the voltage multiplier. The high output voltage (e.g., 23 volts) is achieved using low voltage MOS devices. An output isolation technique is utilized to prevent possible latchup and contention. The operational amplifier also features a bias boot scheme to achieve a faster settling time from power up. In addition, the present invention provides realization of frequency compensation with highest possible breakdown and reduced noise coupling. A bias arrangement between input and output stages of the operational amplifier is used to further help reduce the power drawn from the voltage multiplier and decrease the settling time.

The trimcell differential amplifier circuit can serially shift in trimbits into a latch and serially shift out trimbits without having to program the flash memory trimcells. The final settings of the trimbits can be programmed by means of a high voltage buffer. A non-overlapping clock generator and additional logic is also included to control the circuit.
