13mV drift Stored Voltage (V) Analog Memory Element 8 bit-precise storagecharacteristic 8 bit-precise write characteristic Output Voltage (V) Input Voltage (V) Time (s) Uses a clock to do signal restoration without explicit quantization on voltage Information that has been first converted to time. When time is a signal variable, a clock is a powerful tool for quantization since you round up or round down to the nearest clock edge.
