Item 8.      Other Events.

   On November 13, 2007, the Board of Directors (the "Board") of Micrel,
Incorporated (the "Company") approved a modification to the plan adopted on
November 29, 2006 to repurchase shares of the Corporation's issued and
outstanding Common Stock during calendar year 2007 (the "Plan").  Under the
original Plan, the Company is authorized to repurchase shares of the Company's
issued and outstanding Common Stock, if practical for the Company to do so,
with a value no greater than $50,000,000.00 in the aggregate; provided,
however, that (i) such repurchase transactions shall be in accordance with the
terms of Rule 10b-18 under the Securities Exchange Act of 1934, as amended; and
(ii) such repurchases shall be completed no later than December 31, 2007.

Under the modification to the Plan, the aggregate amount authorized to be used
to repurchase shares in calendar year 2007 is increased to $65,000,000.

As of November 12, 2007, the Company had expended approximately $42.2 million
of the $50 million authorized for the repurchase of common stock in 2007.  The
current repurchase plan approved in November 2006 will terminate on
December 31, 2007.

In addition, as previously disclosed in the Company's Form 10-Q for the quarter
ended September 30, 2007, the Company's Board of Directors has also approved a
$50 million share repurchase program for calendar year 2008 (the "2008 Plan").
The 2008 Plan will take effect after the current Plan terminates.
