Title: Measuring frequency of oscillator in IC without oscillator connection pin - using integrated measurement circuit which varies voltage at integrated circuit supply pin with period of oscillator output
Inventor: WIRTH JENS DIPL ING
IPC: G01R23/06
Filed: 1991-09-18
Abstract: The method of measuring the frequency of an oscillator (OSZ) in an integrated circuit without an oscillator connection pin involves use of an integral measurement (MS) circuit which is periodically driven by the oscillator output. The circuit produces a voltage corresp. to the frequency which can be evaluated at the IC supply voltage connection (P2). The measurement circuit (MS) produces the measurement voltage by periodically varying the supply voltage. The voltage at the supply pin (P2) varies with the periodic duration of the oscillator. ADVANTAGE - Enables measurement of frequency of oscillator in IC even when IC has no oscillator output pin.

Title: Auto-correlation of measuring inaccuracies in lithography system - forming superimposed images of linear and strip grids on high resolution film, subjecting to effect for set time, and observing using microscopic
Inventor: HUEBNER BERND
IPC: G03F9/00
Filed: 1992-03-13
Abstract: The method involves illuminating a linear grid with a corpuscular optical beam-system under investigation and using a high resolution recording film.
