The first topic of this thesis proposes an 8-bit, 20 MSample/s pipeline analog-to-digital converter (ADC). The sharing amplifiers technique is employed to reduce the overall number of the amplifiers wherein dynamic comparators are adopted to reduce the power consumption. The proposed design is implemented by 0.35 £gm CMOS technology. The simulation results show that maximum power consumption is 45 mW given a 3.3 V power supply, and the SFDR is 45 dB with a sinusoidal input at 5 MHz.
The second topic is to describe a 5-bit, 2.4 MSample/s, low power analog-to-digital converter for ZigBee receiver using 868/915 MHz band. The converter uses the successive approximation architecture. By using 0.18 £gm CMOS technology, the simulation results show the worst-case power consumption is merely 449.6 £gW. The converter achieves the maximum differential nonlinearity of 0.3 LSB, the maximum integral nonlinearity of 0.5 LSB.
