Title: Low voltage vco temperature compensation
Inventor: SUTER RICHARD R
IPC: H03B1/00
Filed: 1990-07-17
Abstract: A circuit (10) for temperature compensation of a varactor voltage controlled oscillator control signal (Vtune) includes a proportional to absolute temperature (PTAT) current source (32) and an adjustable, temperature stable current source (34). The difference between these two current sources defines an offset current (I2-I1, 40). The varactor control signal voltage (VIN) is shifted by a predetermined reference voltage (VREF) and offset by an offset voltage proportional to the offset current (I2-I1), in a differential amplifier portion of the circuit (36), to provide a tuning signal (Vtune) for controlling the varactor (DVCO) so as to compensate for the varactor capacitance temperature drift. The adjustable, temperature stable current source (34) allows tuning (R1) the circuit in order to precisely tune the VCO to a desired frequency under a predetermined set of operating conditions in order to correct component and process variations.

Inventor: GRUETZMACHER RICHARD J
IPC: F16B7/04
Filed: 1992-07-17
Abstract: A cutting guide assembly consists of a pair of guide rails in end-to-end abutting relationship with a clamping plate frictionally engaging each guide rail to secure the rails together.  Each guide rail has a cross section defining a channel.  A ramped or inclined lip is disposed within the channel, and is engaged by the end of a flange provided on the clamping plate to force the flange toward an inwardly facing stop surface defined by a wall of the guide rails.  A series of set screws provide relative downward movement of the clamping plate, to cause the end of the flange to ride on the inclined surface and to force an outwardly facing surface of the flange against the stop surfaces of the guide rails.  In this manner, the vertical guide surfaces of the guide rails are automatically aligned with each other when the rails are secured together.  The clamping plate includes a second flange, which engages a supporting surface formed on a second inwardly extending lip.  The second flange moves along the supporting surface during tightening down of the clamping plate, to accommo-date the other flange riding along the inclined surface.
