Review of Analog Devices: High Speed Design Techniques

Go to Analog Devices Design Handbooks (please scroll down and download the High Speed Design Techniques pdf files)

This notes about high speed design techniques are for the advanced reader. Before you can study the specific challenges of high Op Amps and high speed data converters, you should have a solid understanding of their fundamental operation at lower frequencies. But section 7b includes some general information (e.g. about thermal management) that is useful for any circuit designer. By the way, if you are interested in high speed design, you should also have a look at the classic AN47 High Speed Amplifier Techniques by Jim Williams.

Section 1 covers high speed Op Amps and some details about their architecture. The advantages and disadvantages of VFB and CFB OP Amps are discussed.

Section 2, High Speed Op Amps Applications, starts with the important (but difficult) topic of capacitive loading of Op Amps. Other topics are high speed single supply Op Amps, several video applications and high speed photodiode preamps.

Section 3 discusses RF/IF subsystems. Topics covered include dynamic range compression and modulation/demodulation.

Section 4 discusses high speed sampling and high speed A-D converters. It first introduces the basic concepts of sampling and quantization and the effects of distortion and noise. Then high speed A-D converter architectures like successive approximation ADCs and flash ADCs are discussed.

Section 5 covers high speed ADC applications. Much of this section consists of specific information about Analog Devices products, but the chapter about high speed ADC applications in digital receivers provides some general information.

Section 6 covers high speed DACs and DDS systems.

Section 7a about high speed hardware design techniques contains some interesting information about PSpice modelling and about several prototyping techniques.

Section 7b is called Grounding in High Speed Systems, but in covers many other topics too. It starts indeed with a discussion of grounding, but the next topic is power supply noise reduction and filtering, including a disussion of the different types of capacitors and their suitability for high speed systems. The chapter about thermal management is also very interesting. Other topics are EMI/RFI considerations and shielding.

You should also take a look at the other Analog Devices seminar notes.
