Felix Lustenberger received the diploma (M.Sc.) degree in micro engineering from EPFL, Lausanne, Switzerland, in 1995, and the Dr.Sc. Techn. (Ph.D.) degree in electrical engineering from ETHZ, Zurich, Switzerland, in 2000. From 2001 to 2002, he was also with Snowbush Microelectronics, Toronto, ON, Canada, where he developed cutting-edge mixed-signal circuits for high-speed data communications. In 2002, he joined the Photonics Division of CSEM, Zurich, Switzerland and in 2004, he became the Head of the Image Sensing Group dealing with all aspects of high-performance imaging starting at the semiconductor level and going up to the system-design level for metrology systems of ultimate performance. Since 2007, he is with ESPROS Photonics Corp., Landquart, Switzerland.
Dr. Lustenberger is a senior member of several IEEE societies. From 2007 to 2009, he served as the chair of the Analog Signal Processing Technical Committee of the IEEE Circuits and Systems Society.

The time-of-flight (TOF) principle is a well known principle to acquire a scene in all three dimensions. The advantages of the knowledge of the third dimension are obvious for many kinds of applications. The distance information within the scene renders automatic systems more robust and much less complex or even enables completely new solutions. A solid-state image sensor containing 124 x 160 pixels and the corresponding 3D-camera, the so-called SwissRanger camera, has already been presented in detail in [1]. It has been shown that the SwissRanger camera achieves depth resolutions in the sub-centimeter range, corresponding to a measured time resolution of a few tens of picoseconds with respect to the speed of light (c~3•108 m/s). However, one main drawback of these so-called lock-in TOF pixels is their limited capacity to handle background illumination. Keeping in mind that in outdoor applications the optical power on the sensor originating from background illumination (e.g., sun light) may be up to a few 100 times higher than the power of the modulated illumination, the sensor requires new pixel structures eliminating or at least reducing the currently experienced restrictions in terms of background illumination. Based on a 0.6 µm CMOS/CCD technology, four new pixel architectures suppressing background illumination and/or improving the ratio of modulated signal to background signal at the pixel-output level were developed and will be presented in this paper. The theoretical principle of operation and the expected performance are described in detail, together with a sketch of the implementation of the different pixel designs at silicon level. Furthermore, test results obtained in a laboratory environment are published. The sensor structures are characterized in a high background-light environment with up to sun light conditions. The distance linearity over a range of a few meters with the mentioned light conditions is measured. At the same time, the distance resolution is plotted as a function of the target distance, the integration time and the background illumination power. This in-depth evaluation leads to a comparison of the various background suppression approaches; it also includes a comparison with the traditional pixel structure in order to highlight the benefits of the new approaches. The paper concludes by providing parameter estimations which enables the outlook to build a sensor with a high lateral resolution containing the most promising pixel.
