Abstract: A general architecture to correct conversion errors of a multi-stage, pipelined subranging analog-to-digital (A/D) converter includes cascaded stages, (1, 2 ....m), each stage generating (12) a binary conversion signal representing the nearest quantized level below that of the analog input signal and also generating (14,16,18) a residual analog signal applied to the next conversion stage. The binary conversion signals from the several stages address individual or common look-up tables (30) providing compensated binary signals selected to compensate for nonidealities of the A/D converter components. The compensated binary signals from the look-up tables provide a corrected output signal when summed together (32). A simple method of calibration for the A/D converter makes use of a least-mean-squared adaptation algorithm. The A/D converter accommodates practical circuit nonidealities such as component mismatching, gain error and voltage offsets, and handles high levels of amplifier nonlinearity. The architecture is applicable to any subranging converter with arbitrary numbers of stages and bits per stage.

Abstract: A novel method of pattern formation and a projection exposure apparatus are disclosed, in which the pupil of a projection lens of the projection exposure apparatus used for forming an LSI pattern or the like has mounted thereon an optical filter having a complex amplitude transmittance distribution expressed substantially as        T(r) = cos(2πβr² - ϑ/2)           as a function of a radial coordinate r normalized by the maximum radius of the pupil. Alternatively, Fourier transform of a layout pattern drawn on the LSI is obtained, an obtained Fourier transform data is multiplied by        cos(2πβf² - ϑ/2          (where f is a spatial frequency, and β, ϑ appropriate real numbers), the inverse Fourier transform of the resulting product is taken to produce a pattern, and this pattern or an approximate solution thereof is used as a mask pattern thereby to produce an LSI by exposure. As a result, even when the NA is increased and the wavelength shortened to improve the resolution limit, a large depth of focus and a high image quality are obtained at the same time. It is thus possible to form a pattern of 0.2 to 0.3 µm by the use of an optical exposure system.

Abstract: 2.1 In a DC-convertor, it is intended to achieve follow-up control for further output voltages which cannot be influenced by the switching behaviour of the electronic switch used on the primary side. At the same time, it is intended that no significant power loss should occur, especially in the full-load case. 2.2 The further secondary voltages are stabilised by in each case one series control loop which consists of a control transistor which is operated as a controllable resistor. The latter is driven by a differential amplifier which compares a first reference voltage with a second reference voltage which is directly dependent on the output voltage. If the latter falls to a value which is predetermined by the first reference voltage, the control transistor which is switched on to have a low resistance. 2.3 All the output voltages are precisely regulated, and low-resistance switching on occurs when the output voltage reaches the level of the load voltage. <IMAGE>
