“…Optimization algorithms running on the baseband DSP are used to determine perturbations of the tuning knob values that cause the cost metric C to be minimized across multiple testing and tuning iterations. When a DSP is not available, dedicated on-chip circuitry can be used to implement simpler optimization procedures such as the SS-LMS algorithm [8] for tuning purposes. A key benefit here is that data for tuning does not need to be prestored in memory such as for the mapping function described earlier.…”

“…Typically constrained test generation is performed to reflect the capability of the hardware used to generate the test. For example, when testing is performed using software running on the baseband DSP of a transceiver unit, band-limited multitone or transient test stimulus can be used [6][7][8][9][10].…”

Due to the proliferation of nanometer CMOS mixed-signal/RF circuits and a push towards high operating speeds (5-100 Ghz+), there has been renewed interest in the design of high-speed circuits and systems that can self-calibrate and self-heal post-manufacture and in the field. In the past, designers have invented selfhealing mechanisms that are tailored towards specific (critical) mixed-signal/RF performance metrics of specific circuit architectures (transmitter, receiver, etc). What is desired, however, is the ability to monitor multiple performance metrics concurrently and trade them off against one another in an optimal manner, through performance tuning mechanisms, to satisfy system-level Quality of Service (QoS) guarantees. Further, the methods employed must be scalable across different device types/circuit architectures and supported by CAD tools that enable automation of self-healing design procedures.In this paper, recent research advances are presented that allow low cost and rapid selfhealing of complex mixed-signal/RF systems and enable the development of design automation tools to support such activity across diverse performance metrics and circuit types.

“…The sensors extract characteristic device features that are used by the DSP in the regression-based performance prediction for testing [9] or tuning [10] purposes. In a recent work, [8] considers the tuning of RF performances using digital signatures. The Hamming distance between the reference signature and the actual signature is used to control the device, without the need of performance prediction from the observed responses.…”

Abstract. This work presents a new approach for controlling power consumption in RF devices. The approach is based on the definition of application-dependent performance modes for power hungry RF circuits and a logical control strategy that adjusts the power supply of each circuit to the mode required by the application. The control strategy uses embedded sensors, a recursive parameter identification approach and regression models for performance prediction, while demanding minimum embedded resources for computation. The control strategy is robust with respect to circuit parametric deviations due to the manufacturing process or ageing mechanisms. The strategy is illustrated for the case of an RF LNA using envelop detectors as embedded sensors. Simulation results of the control strategy at the transistor-level illustrate the energy savings that can be obtained for an example application.

The demand for richer multimedia services, multifunctional portable devices and high data rates can only been visioned due to the improvement in semiconductor technology. Unfortunately, sub-90 nm process nodes uncover the nanometer Pandora-box exposing the barriers of technology scaling-parameter variations, that threaten the correct operation of circuits, and increased energy consumption, that limits the operational lifetime of today's systems. The contradictory design requirements for low-power and system robustness, is one of the most challenging design problems of today. The design efforts are further complicated due to the heterogeneous types of designs (logic, memory, mixed-signal) that are included in today's complex systems and are characterized by different design requirements. This paper presents an overview of techniques at various levels of design abstraction that lead to low power and variation aware logic, memory and mixed-signal circuits and can potentially assist in meeting the strict power budgets and yield/quality requirements of future systems.
