internal block diagram of the High-Speed Analog Comparator module is shown in Figure 2-1. The analog comparator input pins are typically shared with pins used by the Analog-to-Digital Converter (ADC) module. Both the comparator and the ADC can use the same pins at the same time.

Fig. 1 shows a typical flash ADC block diagram. For an N-bit converter, the circuit employs 2 N-1 comparators. A resistive-divider with 2 N resistors provides the reference voltage. The reference voltage for each comparator is one least significant bit (LSB) greater than the reference voltage for the comparator immediately below it.

low power and low voltage techniques are briefly introduced here and modifications from the pre-vious 1.2µm design [1][2][3] are also included in this section. A prototype chip has been fabricated in 0.6µm DPTM CMOS process and evaluated. The measured results will be presented in Chapter 4. And the conclusion is in Chapter 5. 1.
