Abstract
A multi-stage apparatus used as a voltage controlled oscillator. Each stage includes a first complementary differential current switch and a second complementary differential current switch with a second set of complementary differential current switches having a first complementary differential current switch and a second complementary differential current switch, the two sets of complementary differential current switches are connected in a push pull arrangement. In this arrangement, the outputs of the first complementary differential current switch of the first set of complementary differential current switches and the first complementary differential current switch of the second set of complementary differential current switches are connected with the input of the second complementary differential current switch of the first set of complementary differential current switches. The outputs of the second complementary differential current switch of the first set of complementary differential current switches and the second complementary differential current switch of the second set of complementary differential current switches are connected with the input of the first complementa…
