65nm工艺提供不同的电感和不同的金属层数,安装的时候可选择的具体如下:
- Available metal options are:
- 1 - 1p9m_6X2Z0U_ALRDL
- 2 - 1p9m_6X1Z1U_ALRDL *ind_1z1u *Star_RC *Cal_RC *QRC
- 3 - 1p8m_6X1Z0U_ALRDL *ind_1z
- 4 - 1p8m_6X0Z1U_ALRDL *ind_1u
- 5 - 1p8m_5X2Z0U_ALRDL
- 6 - 1p8m_5X1Z1U_ALRDL *ind_1z1u
- 7 - 1p7m_5X1Z0U_ALRDL *ind_1z
- 8 - 1p7m_5X0Z1U_ALRDL *ind_1u
- 9 - 1p7m_4X2Z0U_ALRDL *Star_RC *Cal_RC *QRC
- 10 - 1p7m_4X1Z1U_ALRDL *ind_1z1u
- 11 - 1p6m_4X1Z0U_ALRDL *ind_1z *Star_RC *Cal_RC *QRC
- 12 - 1p6m_4X0Z1U_ALRDL *ind_1u
- 13 - 1p6m_3X2Z0U_ALRDL
- 14 - 1p6m_3X1Z1U_ALRDL *ind_1z1u
- 15 - 1p5m_3X1Z0U_ALRDL *ind_1z
- *ind_1z1u : Support inductors in RF Process:
- "spiral_std_mu_z", "spiral_sym_mu_z", and "spiral_sym_ct_mu_z"
- *ind_1u : Support inductors in RF Process:
- "spiral_std_mu_a", "spiral_sym_mu_a", and "spiral_sym_ct_mu_a"
- *ind_1z : Support inductors in RF Process:
- "spiral_std_mza_a", "spiral_sym_mza_a", "spiral_sym_ct_mza_a"
- *For more information about inductor support, please refer to PDK_doc/ReleaseNote.txt
复制代码 我查阅了资料,资料里面写:
spiral_std_mu_a : Standard type UTM inductor. (Loop on UTM layer, cross using AL-RDL)
spiral_std_mu_z : Standard type UTM inductor (Loop on UTM layer, cross using metal Z)
spiral_std_mza_a : Standard type logic inductor. (Loop on metal Z and AL-RDL layer, cross using AL-RDL)
spiral_sym_ct_mu_a : Symmetry type UTM inductor. (Loop on UTM layer, cross using AL-RDL)
spiral_sym_ct_mu_z : Symmetry type with central tap UTM inductor. (Loop on UTM layer, cross using metal Z)
spiral_sym_ct_mza_a : Symmetry type with central tap logic inductor. (Loop on metal Z and AL-RDL layer, cross using AL-RDL)
spiral_sym_mu_a : Symmetry type with central tap UTM inductor. (Loop on UTM layer, cross using AL-RDL)
spiral_sym_mu_z : Symmetry type UTM inductor. (Loop on UTM layer, cross using metal Z)
spiral_sym_mza_a : Symmetry type logic inductor. (Loop on metal Z and AL-RDL layer, cross using AL-RDL)
The mu_z type inductors are only supported in top 2 thick with UTM metal options including 1P6M-3X1Z1U, 1P7M-4X1Z1U, 1P8M-5X1Z1U,and 1P9M-6X1Z1U.
The mza_a type inductors are only supported in top 1 thick without UTM metal options including 1P6M-4X1Z0U, 1P7M-5X1Z0U, 1P8M-6X1Z0U.
虽然写的很清楚,但是依然不知道这些代表的含义是啥。
比如说我想要设计一个K波段的LNA,那么现在就有两个问题:
第一:我应该选择多少层的金属比较合适?
第二:对于电感来说我应该选择The mu_z还是应该选择The mza_a呢?
有大神可以给解释下嘛?
