1. 1. Design and Implementation of a high-efficiency low-power analog-to-digital converter for high-speed transceivers

   Master-uppsats, Elektroniksystem; Tekniska högskolan

   Författare :Choudhry Jabbar Younis; [2012]
   Nyckelord :Analog front end; data rates; Analog to digital converter; track and hold; bootstrap; averaging; interpolation;

   Sammanfattning : Modern communication systems require higher data rates which have increased thedemand for high speed transceivers. For a system to work efficiently, all blocks ofthat system should be fast. It can be seen that analog interfaces are the main bottleneckin whole system in terms of speed and power. LÄS MER

3. 2. Design of Highly Linear Sampling Switches for CMOS Track-and-Hold Circuits

   Uppsats för yrkesexamina på grundnivå, Institutionen för systemteknik

   Författare :Muhammad Irfan Kazim; [2006]
   Nyckelord :Switch non-linearities; Bootstrap switch; Bulk-effect compensation switch; Charge injection;

   Sammanfattning : This thesis discusses non-linearities associated with a sampling switch and compares transmission gate, bootstrapping and bulk-effect compensation architectures at circuit level from linearity point of view for 0.35 um CMOS process. All switch architectures have been discussed and designed with an additional constraint of switch reliability. LÄS MER

4. 3. High Speed On-Chip Measurment Circuit

   Uppsats för yrkesexamina på grundnivå, Institutionen för systemteknik

   Författare :Arvid Stridfelt; [2005]
   Nyckelord :Electronics; CMOS; 0.13; sampling; periodic sampling; digital oscilloscope; time equivalent sampling; track and hold; master and slave; sampling clock generator; voltagedivider; source follower; sampling switch; transmission gate; RLC-line; Elektronik;

   Sammanfattning : This master thesis describes a design exploration of a circuit capable of measuring high speed signals without adding significant capacitive load to the measuring node. It is designed in a 0.13 CMOS process with a supply voltage of 1.2 Volt. LÄS MER

5. 4. Sampling Ocsilloscope On-Chip

   Uppsats för yrkesexamina på grundnivå, Institutionen för systemteknik

   Författare :Niklas Forsgren; [2003]
   Nyckelord :Electronics; sampling; high-speed sampling; subsampling; sampling oscilloscope on-chip; source follower; common source; sampling switch; transmission gate; sample and hold; track and hold; MOS transistor; Elektronik;

   Sammanfattning : Signal-integrity degradation from such factors as supply and substrate noise and cross talk between interconnects restricts the performance advances in Very Large Scale Integration (VLSI). To avoid this and to keep the signal-integrity, accurate measurements of the on-chip signal must be performed to get an insight in how the physical phenomenon affects the signals. LÄS MER

7. 5. Implementation and Evaluation of a RF Receiver Architecture Using an Undersampling Track-and-Hold Circuit

   Uppsats för yrkesexamina på grundnivå, Institutionen för systemteknik

   Författare :Magnus Dahlbäck; [2003]
   Nyckelord :Electronics; RF; track-and-hold; undersampling; receiver; noise folding; harmonics aliasing; Elektronik;

   Sammanfattning : Today's radio frequency receivers for digital wireless communication are getting more and more complex. A single receiver unit should support multiple bands, have a wide bandwidth, be flexible and show good performance. To fulfil these requirements, new receiver architectures have to be developed and used. LÄS MER
