  • Pre-charge sample-and-hold circuit
    Publication number: 20080180136
    Abstract: A precharge sample-and-hold circuit is formed by coupling a buffer with an input port and making use of a switch to conduct the circuit between the buffer and a total load capacitor for precharging according the state of a sample-and-hold circuit. When the sample-and-hold circuit is in the sample mode, it precharges the total load capacitor. When the sample-and-hold circuit is in the hold mode, the influence to the sampled signal is further reduced due to the precharging. The requirements of swing rate, output voltage swing, gain-bandwidth product for the opamps can therefore be reduced, hence being applicable to the realization of the design of advanced fabrication technologies of low supply voltages.

Whether a quasi bit 1 is a bit 1 or not is determined according to the critical value, and a total number of the bits 1 within the acquiring time is counted. Similarly, a number of the bits 0 within the acquiring time are also obtained. Thus, the symbol rate is obtained according to the above information.
